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…

A schematic model for QCD I: Low energy meson states
S. Lerma, S. Jesgarz, P. O. Hess +3
A simple model for QCD is presented, which is able to reproduce the meson spectrum at low energy. The model is a Lipkin type model for quarks coupled to gluons. The basic building…
