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…
Exact solution of the spin-isospin proton-neutron pairing Hamiltonian
S. Lerma H., B. Errea, J. Dukelsky +1
The exact solution of proton-neutron isoscalar-isovector (T=0,1) pairing Hamiltonian with non-degenerate single-particle orbits and equal pairing strengths (g_{T=1}= g_{T=0}) is pr…
Exactly-solvable models of proton and neutron interacting bosons
S. Lerma H., B. Errea, J. Dukelsky +2
We describe a class of exactly-solvable models of interacting bosons based on the algebra SO(3,2). Each copy of the algebra represents a system of neutron and proton bosons in a gi…
Exact Solution of the Isovector Proton Neutron Pairing Hamiltonian
J. Dukelsky, V. G. Gueorguiev, P. Van Isacker +3
The complete exact solution of the T=1 neutron-proton pairing Hamiltonian is presented in the context of the SO(5) Richardson-Gaudin model with non-degenerate single-particle level…
