An eigenvalue-based method and determinant representations for general integrable XXZ Richardson-Gaudin models
Pieter W. Claeys, Stijn De Baerdemacker, Mario Van Raemdonck +1
We propose an extension of the numerical approach for integrable Richardson-Gaudin models based on a new set of eigenvalue-based variables. Starting solely from the Gaudin algebra,…

The Dicke model as the contraction limit of a pseudo-deformed Richardson-Gaudin model
Pieter W. Claeys, Stijn De Baerdemacker, Mario Van Raemdonck +1
The Dicke model is derived in the contraction limit of a pseudo-deformation of the quasispin algebra in the su(2)-based Richardson-Gaudin models. Likewise, the integrability of the…
