Maximum Probability Domains for Hubbard Models
Guillaume Acke, Stijn De Baerdemacker, Pieter W. Claeys +4
The theory of Maximum Probability Domains (MPDs) is formulated for the Hubbard model in terms of projection operators and generating functions for both exact eigenstates as well as…
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…
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,…
