Isovector neutron-proton pairing with particle number projected BCS
N. Sandulescu, B. Errea, J. Dukelsky
The particle number projected BCS (PBCS) approximation is tested against the exact solution of the SO(5) Richardson-Gaudin model for isovector pairing in a system of non-degenerate…
Accuracy of BCS-based approximations for pairing in small Fermi systems
N. Sandulescu, G. F. Bertsch
We analyze the accuracy of BCS-based approximations for calculating correlation energies and odd-even energy differences in 2-component fermionic systems with a small number of pai…
Density Matrix Renormalization Group study of Cr and Ni
B. Thakur, S. Pittel, N. Sandulescu
We discuss the development of an angular-momentum-conserving variant of the Density Matrix Renormalization Group (DMRG) method for use in large-scale shell-model calculations of at…
Nuclear Superfluidity and Cooling Time of Neutron-Star Crust
C. Monrozeau, J. Margueron, N. Sandulescu
We analyse the effect of neutron superfluidity on the cooling time of inner crust matter in neutron stars, in the case of a rapid cooling of the core. The specific heat of the inne…
Generic strong coupling behavior of Cooper pairs in the surface of superfluid nuclei
N. Pillet, N. Sandulescu, P. Schuck
With realistic HFB calculations, using the D1S Gogny force, we reveal a generic behavior of concentration of small sized Cooper pairs (2-3 fm) in the surface of superfluid nuclei.…
Pairing interactions and the vanishing pairing correlations in hot nuclei
E. Khan, Nguyen Van Giai, N. Sandulescu
Finite temperature Hartree-Fock-Bogoliubov calculations are performed in Sn isotopes using Skyrme and zero-range, density-dependent pairing interactions. For both stable and very n…
