Editorial proceedings (other academic/artistic)abstract
- It is our great pleasure to dedicate this special issue of Journal of Plasma Physics to our dear friend and colleague Professor Padma Kant Shukla on the occasion of his 60th birthday on 7th July 2010. Padma is one of the most prominent and productive scientists in plasma physics and in neighboring fields, and has published more than 1300 papers in scientific journals. It has for some time been the aim of his friends to honor him on this occasion, and earlier this year we sent out invitations to distinguished scientists who have collaborated with Padma over the years. The response has been overwhelming, and we collected 43 manuscripts, covering a diverse range of topics in plasma physics, which are now published in this issue. We believe that these papers reflect some of the impact of Padma's research in plasma physics.

3D electron fluid turbulence at nanoscales in dense plasmas

Journal article (peer-reviewed)abstract
- We have performed three-dimensional (3D) nonlinear fluid simulations of electron fluid turbulence at nanoscales in an unmagnetized warm dense plasma in which mode coupling between wave function and electrostatic (ES) potential associated with underlying electron plasma oscillations (EPOs) lead to nonlinear cascades in inertial range. While the wave function cascades towards smaller length scales, ES potential follows an inverse cascade. We find from our simulations that the quantum diffraction effect associated with a Bohm potential plays a critical role in determining the inertial range turbulent spectrum and the subsequent transport level exhibited by the 3D EPOs.

Numerical study of the magnetic electron drift vortex mode turbulence in a nonuniform magnetoplasma
- 2009

In: Physical Review E. Statistical, Nonlinear, and Soft Matter Physics. - : American Physical Society. - 1063-651X .- 1095-3787. ; 79:6, s. 066404-066410

Journal article (peer-reviewed)abstract
- Asimulation study of the magnetic electron drift vortex (MEDV) modeturbulence in a magnetoplasma in the presence of inhomogeneities inthe plasma temperature and density, as well as in theexternal magnetic field, is presented. The study shows that theinfluence of the magnetic field inhomogeneity is to suppress streamerlikestructures observed in previous simulation studies without background magnetic fields.The MEDV mode turbulence exhibits nonuniversal (non-Kolmogorov-type) spectra for differentsets of the plasma parameters. In the presence of aninhomogeneous magnetic field, the spectrum changes to a 7/3 powerlaw, which is flatter than without magnetic field gradients. Therelevance of this work to laser-produced plasmas in the laboratoryis briefly mentioned.
