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…
Breached pairing in trapped three-color atomic Fermi gases
Beatriz Errea, Jorge Dukelsky, Gerardo Ortiz
We introduce an exactly solvable model for trapped three-color atom gases. Applications to a cigar-shaped trapped cold fermions reveal a complex structure of breached pairing phase…
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…
SU(3) Richardson-Gaudin models: three level systems
S. Lerma H., B. Errea
We present the exact solution of the Richardson-Gaudin models associated with the SU(3) Lie algebra. The derivation is based on a Gaudin algebra valid for any simple Lie algebra in…
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…
