- Isoscalar pairing interaction and nuclear symmetry energy are investigated by means of the iso-cranking technique. Iso-cranking represents the lowest order approximation to isospin projection after variation. Due to its internal simplicity, it offers a very intuitive understanding of the structure of the nuclear symmetry energy as well as the response of the isoscalar and isovector pairing versus isospin.

Forskningsöversikt (refereegranskat)abstract
- Recent high-spin observations reveal entirely new modes of collective rotational motion and the existence of novel symmetries and spontaneous symmetry breaking phenomena, uncovering hitherto unexploited coupling schemes of intrinsic and collective degrees of freedom. It continues to stimulate the theoretical progress in the field, which clearly turns towards a microscopic description based on self-consistent approaches using either an effective non-relativistic Hamiltonian or an effective relativistic Lagrangian. New coupling schemes call not only for symmetry unrestricted mean-field theories, but also for extensions going beyond the mean-field. The progress in the development of these theoretical methods is discussed in this review.

Probing spin fields and spin-orbit term of the local nuclear energy functional at band termination
- 2005

Tidskriftsartikel (refereegranskat)abstract
- A systematic study of the terminating states in A similar to 50 mass region using the self-consistent Skyrme-Hartree-Fock model is presented. The objective is to use the intrinsic simplicity of the terminating states to constrain certain parameters of the local nuclear energy functional. In particular, the work focuses on the spin fields and the spin-orbit term and constrain the appropriate Landau parameters and the strength of the spin-orbit potential.

- A systematic study of terminating states in the Asimilar to50 mass region using the self-consistent Skyrme-Hartree-Fock model is presented. The objective of this study is to demonstrate that the terminating states, due to their intrinsic simplicity, offer unique and so far unexplored opportunities to study different aspects of the effective NN interaction or nuclear local energy density functional. In particular, we show that the agreement of the calculations to the data depends on the spin fields and the spin-orbit term which, in turn, allows us to constrain the appropriate Landau parameters and the strength of the spin-orbit potential. The present study reveals that the structure and energy of terminating states can be used as a tool to differentiate among the many Skyrme force parametrizations.
