- In this chapter we give a selective review of our work on the role of electron correlation in the theory of high-temperature superconductivity (HTSC). The question of how electronic repulsions might give rise to off-diagonal long-range order (ODLRO) in high-temperature superconductors is currently one of the key questions in the theory of condensed matter. This chapter argues that the key to understanding the occurrence of HTSC in cuprates is to be found in the Bohm-Pines Hamiltonian, modified to include a polarizable dielectric background. The approach uses reduced electronic density matrices and discusses how these can be used to understand whether ODLRO giving rise to superconductivity might arise from a Bohm-Pines-type potential which is comprised of a weak long-range attractive tail and a much stronger short-range repulsive Coulomb interaction. This allows time-reversed electron pairs to undergo a superconducting condensation on alternant cuprate lattices. Thus, a detailed summary is given of the arguments that such interacting electrons can cooperate to produce a superconducting state in which time-reversed pairs of electrons effectively avoid the repulsive hard-core of the interelectronic Coulomb interaction but reside on average in the attractive well of the effective potential. In a superconductor the plasma wave function becomes the longitudinal component of a massive photon by the Anderson-Higgs mechanism. The alternant cuprate lattice structure is the key to achieving HTSC in cuprates with d(x2) - (y2) symmetry condensate symmetry.

- The question as to how off-diagonal long-range order (ODLRO) might arise from repulsive electron correlations in high-temperature superconductors is investigated. The review makes a fuller explanation of our recent work on this topic which is currently a central issue in the theory of high-temperature superconductivity. Particularly, we study the issue as to whether ODLRO can arise from repulsive electronic correlations. Pairs of electrons on Cuprate and the iron-based pnictide and chalcogenide alternant lattices may have a weak long-range attractive tail and much stronger short-range repulsive Coulomb interaction. The long-range attractive tail may find its origin in one of the many proposals for high-Tc superconductor and thus has an uncertain origin. Some possibilities arise from Friedel-type oscillations or polarization of the background but ultimately these must reflect the alternant nature of the lattice structure. Here, we make it plausible that such interacting electrons can cooperate to produce a superconducting state in which time-reversed pairs of electrons effectively avoid the repulsive part but dwell on average in the attractive region of the potential. The alternant lattice structure is thus central to the occurrence of most stable high-temperature superconductivity with dx2-y2 or sign alternating s-wave or s± condensate symmetries.

- Consciousness is the ability to have intentionality, which is a process that operates at various temporal scales. To qualify as conscious, an artificial device must express functionality capable of solving the Intrinsicality problem, where experienceable form or syntax gives rise to understanding 'meaning' as a noncontextual dynamic prior to language. This is suggestive of replacing the Hard Problem of consciousness to build conscious artificial intelligence (AI). Developing model emulations and exploring fundamental mechanisms of how machines understand meaning is central to the development of minimally conscious AI. It has been shown by Alemdar and colleagues [New insights into holonomic brain theory: implications for active consciousness. Journal of Multiscale Neuroscience 2(2023), 159-168] that a framework for advancing artificial systems through understanding uncertainty derived from negentropic action to create intentional systems entails quantum-thermal fluctuations through informational channels instead of recognizing (cf., introspection) sensory cues through perceptual channels. Improving communication in conscious AI requires both software and hardware implementation. The software can be developed through the brain-machine interface of multiscale temporal processing, while hardware implementation can be done by creating energy flow using dipole-like hydrogen ion (proton) interactions in an artificial 'wetwire' protonic filament. Machine understanding can be achieved through memristors implemented in the protonic 'wetwire' filament embedded in a real-world device. This report presents a blueprint for the process, but it does not cover the algorithms or engineering aspects, which need to be conceptualized before minimally conscious AI can become operational.

Samlingsverk (redaktörskap) (refereegranskat)abstract
- In this issue of the Advances in Quantum Chemistry, Volume 66, the readers are offered an interesting mix of themes, first an account of the high-Tc mechanism of a recently discovered class of superconductors, with a characteristic alternant lattice structure; a lucid treatise of some of the fundamental core concepts, labeled as conundrums in chemical physics, a state-of-the art description of the electron-dynamics, END, method; and finally new developments regarding unified descriptions of embeddings in both a discrete and a continuum polarizable environment within multiconfigurational self-consistent field (MCSCF) theories. In Chapter 1, the authors review a contemporary hot topic, that is, theories concerning the understanding of a newly discovered class of high-Tc superconductors, that is, the iron-based pnictides and the chalcogenic compounds exhibiting, in analogy with the cuprates previously discovered and discussed, a characteristic alternant lattice structure. Since recent speculations suggest the emergence of superconductivity from repulsive electronic correlations, the authors demonstrate in this review a detailed mechanism for this class of condensates originating in the alternant structure as well as simultaneously exhibiting Yang’s celebrated concept of off-diagonal long-range order, ODLRO. In addition, it is pointed out that the authors proposed conformational stabilization with strong interactions as a possible mechanism for high-temperature superconductivity more than 30 years ago and that a similar repulsive coulomb mechanism for the alternant lattice structure is central to the occurrence of the most stable condensates, exhibiting dx2-y2symmetry for the cuprates and sign alternating s-wave or s±condensate symmetries for the pnictides. In Chapter 2, several fundamental concepts and models that appear challenging to students and teachers in chemistry interrelated scientific disciplines have been presented under the title “Conundrums in Chemical Physics.” In particular, the author provides explanations and validations of concepts such as those of the classical Marcus model and the quantum mechanical Landau theory of electron transfer reactions, or further the semi-classical Landau–Zener approach for diabatic transitions, integrated by the notion of reaction paths as well as the progression of stochastic models, etc. In addition, fundamental mathematical approaches, like the Langevin-, the Fokker–Planck-, and the Klein–Kramers’ equation, are illustrated and evolved. Possible objections of the work presented here concern the connection between Kramers’ account of Transition State theory in the context of phase space diffusion and the irreversible version of the Liouville equation. By transferring the classical concepts to the field of Quantum Chemistry, the author meets the complaints and outlines a time-dependent Liouville superoperator space and Trace Algebra with an emphasis to facilitate the description of the issues facing the developmentof a modern quantum mechanical theory of irreversible processes in analogy with their classical counterparts. Chapter 3 concerns a method for treating molecular dynamics in a nonadiabatic way that treats electrons and nuclei simultaneously. The method, electron nuclear dynamics or END, as presently implemented, reduces the nuclear wavefunction to zero width, making the nuclei act classically, while maintaining Thouless single-determinantal description of the electrons. Typically, the method is implemented in its simplest form and thus has some application problems, as described in this chapter. The chapter deals with the computational simplification of the problem by introducing a density functional (DFT)-based treatment of the electronics in order to include some correlation and yet maintain a single-determinantal description. Chapter 4 in this volume deals with the linear response properties of an electronic state of a system embedded in a polarizable medium. The treatmentis based on an MCSCF theory and leads to the description of the electronic state of an embedded molecule.The content of this volume is quite diverse, and it is hoped that the volume will provide an interesting read for all who have interest in the quantum mechanical description of a wide variety of molecular systems.

New insights into holonomic brain theory : implications for active consciousness

Tidskriftsartikel (refereegranskat)abstract
- This pioneering research on how specific molecules deep inside our brains form a dynamic information holarchy in phase space, linking mind and consciousness, is not only provocative but also revolutionary. Holonomic is a dynamic encapsulation of the holonic view that originates from the word “holon” and designates a holarchical rather than a hierarchical, dynamic brain organization to encompass multiscale effects. The unitary nature of consciousness being interconnected stems from a multiscalar organization of the brain. We aim to give a holonomic modification of the thermodynamic approach to the problem of consciousness using spatiotemporal intermittency. Starting with quasiparticles as the minimalist material composition of the dynamical brain where interferences patterns between incoherent waves of quasiparticles and their quantum-thermal fluctuations constrain the kinetic internal energy of endogenous molecules through informational channels of the negentropically-derived quantum potential. This indicates that brains are not multifractal involving avalanches but are multiscalar, suggesting that unlike the hologram, where the functional interactions occur in the spectral domain, the spatiotemporal binding is multiscalar because of self-referential amplification occurring via long-range correlative information. The associated negentropic entanglement permeates the unification of the functional information architecture across multiple scales. As such, the holonomic brain theory is suitable for active consciousness, proving that consciousness is not fundamental. The holonomic model of the brain’s internal space is nonmetric and nonfractal. It contains a multiscalar informational structure decoded by intermittency spikes in the fluctuations of the negentropically-derived quantum potential. It is therefore, a more realistic approach than the platonic models in phase space.

- A Zero-Energy Universe Scenario (ZEUS) is portrayed and its implications are examined and clarified. The formulation is based on the algebra of observables, e.g. the momentum-energy and their canonical conjugate partner space-time. Operators represent them in quantum theory and classical canonical variables in nonquantum applications. Conjugate operator/variable arrays impart a united edifice for a zero-energy universe scenario, which corresponds to using a non-positive definite metric for the manifestation of unstable states as recently employed in the field of chemical physics. Analogous formulations within a general complex symmetric setting provide a compelling analogy between Einstein’ s theory of general gravity and Gödel’ s first incompleteness theorem. This scenario brings together up-to-date theories in chemical physics with modern research in biology, physics, and astronomy. This unification establishes an edifice for the various arrows of time as well as authenticates Darwin’ s Paradigm of Evolution from the microscopic realm to the cosmological domain.

Frontiers in Quantum Methods and Applications in Chemistry and Physics : Selected Proceedings of QSCP-XVIII (Paraty, Brazil, December, 2013)
- 2015. - A29
-
Bok (refereegranskat)abstract
- This volume collects 15 selected papers from the scientific contributions presented at the Eighteenth International Workshop on Quantum Systems in Chemistry, Physics, and Biology (QSCP-XVIII), which was organized by Prof. M.A.C. Nascimento at the Casa da Cultura in Paraty (Rio de Janeiro), Brazil, from December 1 to 7, 2013. Over 100 scientists from 25 countries attended this meeting. Participants of the QSCP-XVIII workshop discussed the state of the art, new trends, and future evolution of methods in molecular quantum mechanics, and their applications to a wide variety of problems in chemistry, physics, and biology. The high-level attendance attained in this conference was particularly gratifying. It is the renowned interdisciplinary nature and friendly feeling of QSCP meetings that make them such successful discussion forums. Paraty is located in the south coast of Brazil, 250 km from Rio de Janeiro, the state capital. This historical town, nestled on the Costa Verde, is a living memory of the Gold Cycle: gold extracted from the mines of the state of Minas Gerais was transported by mule along the Estrada Real down to Paraty and from there shipped to Rio de Janeiro. The area of Paraty is probably the only place on the planet that brings together a native forest about 80 % preserved, a bay protected from the open sea by over a hundred islands, and a seventeenth-century town which is regarded by UNESCO as the most harmonious baroque location in the world. From this past originate the relics and traditions that so enchant the visitors: a wonderful wealth of cultural and ecological attractions, as well as a tourist infrastructure consisting of cosy inns and picturesque restaurants. Details of the Paraty meeting, including the scientific program, can be found on the web site: http://www.qscp2013.iq.ufrj.br. Altogether, there were 18 morning and afternoon sessions, where 55 plenary talks were given, and two evening poster sessions, with 18 fl ash presentations for a total of 38 displayed posters. We are grateful to all participants for making the QSCP-XVIII workshop a stimulating experience and a great success. QSCP-XVIII followed the traditions established at previous workshops: QSCP-I, organized by Roy McWeeny in 1996 at San Miniato (Pisa, Italy);QSCP-II, by Stephen Wilson in 1997 at Oxford (England);QSCP-III, by Alfonso Hernandez-Laguna in 1998 at Granada (Spain);QSCP-IV, by Jean Maruani in 1999 at Marly-le-Roi (Paris, France);QSCP-V, by Erkki Brä ndas in 2000 at Uppsala (Sweden);QSCP-VI, by Alia Tadjer in 2001 at Sofi a (Bulgaria);QSCP-VII, by Ivan Hubac in 2002 near Bratislava (Slovakia);QSCP-VIII, by Aristides Mavridis in 2003 at Spetses (Athens, Greece);QSCP-IX, by Jean-Pierre Julien in 2004 at Les Houches (Grenoble, France);QSCP-X, by Souad Lahmar in 2005 at Carthage (Tunisia);QSCP-XI, by Oleg Vasyutinskii in 2006 at Pushkin (St Petersburg, Russia);QSCP-XII, by Stephen Wilson in 2007 near Windsor (London, England);QSCP-XIII, by Piotr Piecuch in 2008 at East Lansing (Michigan, USA);QSCP-XIV, by Gerardo Delgado-Barrio in 2009 at El Escorial (Madrid, Spain);QSCP-XV, by Philip Hoggan in 2010 at Cambridge (England);QSCP-XVI, by Kiyoshi Nishikawa in 2011 at Kanazawa (Japan);QSCP-XVII, by Matti Hotokka in 2012 at Turku (Finland).The lectures presented at QSCP-XVIII were grouped into nine areas in the field of Quantum Systems in Chemistry, Physics, and Biology , ranging from Concepts and Methods in Quantum Chemistry and Physics through Molecular Structure and Dynamics, Reactive Collisions and Chemical Reactions, to Computational Chemistry, Physics, and Biology. The width and depth of the topics discussed at QSCP-XVIII are refl ected in the contents of this volume of proceedings in the book series Progress in Theoretical Chemistry and Physics, which includes four sections:I. Quantum Methodology (3 papers);II. Structure and Properties (4 papers);III. Molecular Dynamics (4 papers);IV. Fundamental Theory (3 papers).In addition to the scientifi c program, the workshop had its usual share of cultural events. There was a boat cruise in the Paraty bay and a show by the internationally known group Contador de Estórias . The award ceremony of the CMOA Prize and Medal took place during the congress banquet in the most traditional restaurant of Paraty, Margarida Café. The CMOA Prize was shared between two selected nominees: Jer-Lai Kuo and Yuan-Chung Cheng, both from Taiwan. Two other nominees, Jhih-Wei Chu (from Taiwan) and Andriy Loboda (from Ukraine) received a certifi cate of nomination and a gift. The prestigious CMOA Medal for senior scientists was awarded to Prof. Lorentz Cederbaum (University of Heidelberg, Germany). According to a custom of QSCP meetings, the venue of the next yearly workshop was announced to be in Odessa, Ukraine, in 2015, followed by one in Taipei, Taiwan, in 2016. However, due to the political events, the dates of the two meetings were later reversed. We are pleased to acknowledge the generous support given to the QSCP-XVIII conference by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), the City of Paraty Convention Bureau and Casa da Cultura of Paraty. We are most grateful to all members of the Local Organizing Committee for their work and dedication, which made the stay and work of participants both pleasant and fruitful. We also thank the members of the International Scientifi c Committee and the Honorary Committee for their invaluable expertise and advice. We hope the readers will fi nd as much interest in consulting these proceedings as the participants in attending the meeting.M.A.C. NascimentoJean MaruaniErkki J. BrändasGerardo Delgado-Barrio

- This is a short introduction as a complement to the Preface, for those not familiar with the current view of pre-existing quantum biology as a re-evolving subject and its influences concerning the theme “quantum boundaries of life.” We suggest that the information-based quantum Darwinism encapsulates macroscopic quantum potentialities via self-referential amplification. It is shown to play a pivotal role, giving support to the signature of life and consciousness at the quantum-classical transition zone where long-range correlative information is cultivated by energy-entropy dissipation in organisms at multiple levels of hierarchical and functional organization.

- This article honours Michael Baer on the occasion of his 80th birthday and celebrates his scientific contributions to non-adiabatic chemical physics. This undertaking prompts the presentation of a first principles molecular theory of the genetic code. Jacques Monod's classic essay, 'Chance and Necessity', is exercised as a platform for this discussion. In particular the controversial concept of teleonomy is considered and evaluated in relation to modern developments in chemical physics.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- PREFACE Advances in Quantum Chemistry provides researchers in quantum chemistry, physical chemistry and chemical physics with up-to-date surveys, invited reviews and highlights of recent achievements. Although the field of quantum chemistry has emerged as a subject of its own it overlaps fundamentally with other fields like applied mathematics, theoretical biology, signal processing including applications in medicine.In the present volume, the readers are presented with an exciting combination of themes, i.e. a description of anti-ferromagnetism in copper oxide, proton-conducting mechanism in solid oxide fuel cells, time-dependent processes in molecular processes, the essence of chemical bonding, biological models for repair of cellular radiation damage, momentum space methods for accurate molecular electronic structure calculations and functional theoretic models for hydrogen bonding networks and proton wires in water oxidation reactions. The first chapter in this volume Chapter, by Kimichika Fukushima, deals with the description of antiferromagaetism in copper oxides using density functional theory. This is a longstanding problem, and the solution is discussed in terms of the variational method based SIWB (surrounding or solid Coulomb-potential-induced well for basis set) scheme. The characteristics of the well stabilizing the O2- ion and making antiferromagaetism possible are discussed. In the second chapter Taku Onishi investigates proton-conducting mechanisms in solid electrolyte oxide fuel cells. Specifically LaAlO3 perovskite is allegedly proposed and compared with conventional perovskite-type conductors. The analysis, based on hybrid Kohn-Sham density functional theory, characterizing the proton conducting pathways, confronts mechanism elucidation and material design, including safety aspects regarding the conflicts with oxide ion conduction. In particular as the oxygen vacancy, doped to incorporate the proton, may conflict with oxide ion conduction, it was concluded, when utilizing LaAlO3 that the temperature strictly regulates the prevention of coincident oxide ion conduction. In Chapter 3, Yngve Öhrn presents and discusses a time dependent treatment of molecular processes. The scheme, known as electron nuclear dynamics (END), is described in formal detail wich includes the choice of coordinate system and its effect on the molecular Hamiltonian, the choice of molecular wave function and the particular role of the time-dependent parameters that originates in a coherent state representation is discussed. References are given to some of the work done with ENDYNE. Chapter 4 concerns chemical bonding. In the present contribution, Elena Sheka describes her experiences of chemical bonds in various investigations of structural chemistry. The investigations comprise a rich selection of chemical compounds from single, double and triple bonds, involving carbon, to provoking the main issues of modern chemistry devoted to fullerenes and recently graphene, the famous nobeliated 2D solid. The structures investigated permit a rather simple methodology based on the odd electron strategy, predominantly advocated by the author. In chapter 5, Dževad and Karen Belkić, advance their notable input to a far-reaching and across-the-board biophysical and chemical analysis of surviving fractions of irradiate cells and their new mechanistic repair-based Padé linear-quadratic model, PLQ. As current dose planning systems in radiotherapy, based on linear-quadratic models (LQ), is satisfactory only at low doses and inadequate for treatment modalities, or hyperfractionation, it is demonstrated that PLQ significantly outperforms LQ models regarding cell survival fractions including saturation effects. Although Gaussian technology has greatly simplified mainstream quantum chemistry, it is a cognizant fact that exponential-type orbitals, ETO’s, are better suited for molecular electronic structure calculations. In chapter 6, James and John Avery contribute to new progress in quantum chemistry by using Fock’s projection of 3D momentum space to 4D hyperspherical harmonics. The authors exploit their extraordinary competence in treating so-called Coulomb Sturmians to derive a general mathematical theorem including elegant, rapid and accurate evaluations of appropriate quantum mechanical molecular integrals. The ensuing closed form expression is illustrated by adequate examples. The final contribution to this volume, Chapter 7 by Yamaguchi et al., uses a QM/MM method to calculate complicated properties of water oxidation in the biosystem known as photosystem II (PSII). Water oxidation in the oxygen evolving complex of PSII is dependent on the hydrogen-bonding networks. The QM/MM computations elucidate the network structures: hydrogen–bonding O…. O(N) and O…H distances and O(N)-H…O angles in PRP, together with the Cl-O(N) and Cl…H distances and O(N)-H…Cl angles for chloride anions. The results are compared with experiment. As advertised, the contents of this volume are multifarious as regards both fundamental theory and innovative applications. The contributing authors have made great strides to share their insights with the reader of the Advances. As series editors, we hope that the present volume will impart the same pleasure and enjoyment as we faced during the preparation of this volume. John R. Sabin and Erkki J. Brändas

- A first principle representation of integrated quantum thermal correlations of autaptic neurons associated with conscious brain mechanisms is proposed – the former termed the retinoid system by Trehub. Within this formulation, one descends on a set of unitary transformations yielding generic symmetries of the reduced neuronal dynamics illustrating the projection of the abstract degrees of freedom onto 3D space. The actual spatio-temporal symmetry suggests a general mirroring interpretation of the autapse as given by the structure of the neuronal network. The theory prompts a motif for the abundance of chemical synapses from a neuron onto itself and provides a simple explanation of the phi phenomenon and the Necker cube optical illusion.

Quantum Darwinism and entropy

-
Bokkapitel (refereegranskat)abstract
- In this chapter we will highlight and broaden the concept of Quantum Darwinism to incorporate an extension to thermodynamic open systems. The strategy will be a bit different compared to the conventional approach in that the formulation, rather than offering a fundamental discussion of the classical measurement problem, derives a more general steady-state picture, where ultimately the dissipative organization of the quantum system is properly thermalized and spatio-temporally tuned from first principles. Two cases will be discussed: (i) the human brain and (ii) the black hole. Both are treated as open non-equilibrium systems, where the brain, conjugate to the mind, exhibits negentropic gain, and a thermo-qubit syntax for communication. The second example, a quantum analogue of a black hole, is demonstrated to exhibit Hawking radiation including the explicit connection between the black hole surface area and the entropy. The results are derived from the axiomatic structure of pioneering quantum chemistry with rigorous extensions to open system adaptation in the Schrödinger-Liouville-Bloch formalism at steady state conditions. The approach suggests a prolegomenon for Hilbert's sixth problem.

Some Biochemical Reflections on Information and Communication

Konferensbidrag (refereegranskat)abstract
- The biochemical aspects of communication have been investigated via anextended framework of original quantum-statistical concepts. The key idea developsfrom the notion of a so-called Spatio-Temporal Neumatic, STN, configuration,an open dissipative structure resting on the boundaries connecting micro-, meso- and macroscopic levels. In this category one finds de novo self-organization of molecular motion, enzymatic catalysis and the self-assembly of nano-structures all the way to biologically relevant processes like cell evolution, cellular neurobiology etc. The possibility to store and communicate coded messages in this enlarged organization is documented and recognized, unifying various proposals of theoretical understanding including in particular the law of Gödelian self-reference. It is demonstrated that intra-cell and inter-cell order leads to differentiation through a Poissonian modus operandi. The latter lacks intrinsic memory, but its statistical nature gives way to something non-intrinsic of teleonomic significance. Various consequences of this idea prompt a broadened notion of communication and information, generating encodable cell differentiation through cell quality value factors resonating through original communication channels accessible through Poisson statistics. It is shown that inter-cell communication is temporally dominated while intra-cell information is largely spatio-controlled. The nested (spatio-temporal) property of the “code of codes” extends from the genetic- through the socio-, ecological- and to the cosmological rank, while taking account of a more stringent and appraisable representation of the contemporary concept of a meme.

- In this communication we take up the age-old problem of the possibility to incorporate quantum jumps. Unusually, we investigate quantum jumps in an extended quantum setting, but one of rigorous mathematical significance. The general background for this formulation originates in the Balslev-Combes theorem for dilatation analytic Hamiltonians and associated complex symmetric representations. The actual jump is mapped into a Jordan block of order two and a detailed derivation is discussed for the case of the emission of a photon by an atom. The result can be easily reassigned to analogous cases as well as generalized to Segrè characteristics of arbitrary order.

- We define precognitive affect, composed of information holding dispositional states, as noncontextual, rudimentary building blocks of subjective intentionality. We take on a psychodynamic approach to intentional agency. Intentions unfold into actions in animate thermodynamics reducing subjective uncertainty by negentropic action. They are intentions in action carrying meaning in species having complex protein interactions with various regulated gene sets. In particular, the unfolding of intentionality in terms of biological purpose introduced by subjective functioning allows for a satisfactory account of subjective intentionality. The underlying experience of acting paves the way for understanding meaning of precognitive affect from subjective functioning. Therefore, the brain’s subjective intentionality as the underlying experience of acting is embedded in a negentropic “consciousness code” of “hidden” thermodynamic energy. It is the negentropically-derived quantum potential energy in the unified functioning of brain consciousness at the macroscopic scale. While at the mesoscopic scale, Schrödinger processes create boundary conditions for negentropic action to inform the intentional agency.

- We wish to suggest a mechanism for binding intrinsic information based on an inter-cerebral superfast, spontaneous information pathway involving protein-protein interactions. Protons are convenient quantum objects for transferring bit units in a complex water medium like the brain. The phonon-polariton interaction in such a medium adds informational complexity involving complex protein interactions that are essential for the superfluid-like highway to enable the consciousness process to penetrate brain regions due to different regulated gene sets as opposed to single region-specific genes. Protein pathways in the cerebral cortices are connected in a single network of thousands of proteins. To understand the role of inter-cerebral communication, we postulate protonic currents in interfacial water crystal lattices result from phonon-polariton vibrations, which can lead in the presence of an electromagnetic field, to ultra-rapid communication where thermo-qubits, physical feelings, and protons that are convenient quantum objects for transferring bit units in a complex water medium. The relative equality between the frequencies of thermal oscillations due to the energy of the quasi-protonic movement about a closed loop and the frequencies of electromagnetic oscillations confirms the existence of quasi-polaritons. Phonon-polaritons are electromagnetic waves coupled to lattice vibrational modes. Still, when generated specifically by protons, they are referred to as phonon-coupled quasi-particles, i.e., providing a coupling with vibrational motions. We start from quasiparticles and move up the scale to biomolecular communication in subcellular, cellular and neuronal structures, leading to the negentropic entanglement of multiscale ‘bits’ of information. Espousing quantum potential chemistry, the interdependence of intrinsic information on the negative gain in the steady-state represents the mesoscopic aggregate of the microscopic random quantum-thermal fluctuations expressed through a negentropically derived, temperature-dependent, dissipative quantum potential energy. The latter depends on the time derivative of the spread function and temperature, which fundamentally explains the holonomic brain theory.

- This paper proposes biophysical principles for why geometric holonomic effects through the geometric vector potential are sentient when harmonized by quantized magnetic vector potential in phase-space. These biophysical principles are based on molecular level electromagnetic resonances in partially holistic molecules where nonintegrated information acts as the consciousness process’s conduit—using the informational structure of physical feelings as a transition into subjectivity. The transformation of internal energies from potential to kinetic as ‘concealed’ motion may measure the causal capacity required to bridge causality for conscious experience. Conformational transitions produce bond-breaking, resulting in boundary conditions and limiting the molecular wavefunction to a partially holistic molecular environment with molecular holonomic effects. The van der Waals energy increases protein conformational activity (re-arrangement of bonds), causing energy transfer and information in protein-protein interactions across the cerebral cortex through the energy transduction process. Energy transitions predetermine molecular level electromagnetic resonances in aromatic residues of amino acids. The energy sharing between various nested molecular level electromagnetic resonances interacting with the intermolecular adhesion of London forces at the nexus between phospholipids and the lipophilic proteins has a key role in constraining the release of energy resulting in a vast array of information-based action through negentropic entanglement. Such information structure, passing from the objectivity of holonomic effects stemming from molecular level electromagnetic resonances, has an inherent ambiguity since meaning cannot be related to context, which constitutes preconscious experienceability. The transition from potentiality to actuality where Coulombic force is expressed as a smear of possible experiences where carriers of evanescent meanings instantly actualize through intermittent dispersion interactions as conscious experiences and return to potentiality in preconscious experienceabilities.
