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…
Density matrix renormalization group approach to two-fluid open many-fermion systems
J. Rotureau, N. Michel, W. Nazarewicz +2
We have extended the density matrix renormalization group (DMRG) approach to two-fluid open many-fermion systems governed by complex-symmetric Hamiltonians. The applications are ca…
Cooper pairs in atomic nuclei
G. G. Dussel, S. Pittel, J. Dukelsky +1
We consider the development of Cooper pairs in a self-consistent Hartree Fock mean field for the even Sm isotopes. Results are presented at the level of a BCS treatment, a number-p…
Generalized Richardson-Gaudin Nuclear Models
J. Dukelsky, V. G. Gueorguiev, P. Van Isacker
The exact solvability of several nuclear models with non-degenerate single-particle energies is outlined and leads to a generalization of integrable Richardson-Gaudin models, like…
The Pairing interaction in nuclei: comparison between exact and approximate treatments
J. Dukelsky, G. G. Dussel, J. G. Hirsch +1
As a model for a deformed nucleus the many level pairing model (picket fence model with ~100 levels) is considered in four approximations and compared to the exact solution given b…
The Density Matrix Renormalization Group Method for Realistic Large-Scale Nuclear Shell-Model Calculations
S. S. Dimitrova, S. Pittel, J. Dukelsky +1
The Density Matrix Renormalization Group (DMRG) method is developed for application to realistic nuclear systems. Test results are reported for 24Mg.
