Eigenvalue-based determinants for scalar products and form factors in Richardson-Gaudin integrable models coupled to a bosonic mode
Pieter W. Claeys, Stijn De Baerdemacker, Mario Van Raemdonck +1
Starting from integrable (quasi-)spin Richardson-Gaudin XXZ models we derive several properties of integrable spin models coupled to a bosonic mode. We focus on the Dicke-J…
