Degeneracies in a nonintegrable pairing model
J. Okolowicz, M. Ploszajczak, J. Dukelsky
The evolution pattern of exceptional points is studied in a non-integrable limit of the complex-extended 3-level Richardson-Gaudin model. The appearance of a pseudo-diabolic point…

Unexpected features of quantum degeneracies in a pairing model with two integrable limits
J. Dukelsky, J. Okolowicz, M. Ploszajczak
The evolution pattern of level crossings and exceptional points is studied in a non-integrable pairing model with two different integrable limits. One of the integrable limits has…
