"Bethe-Ansatz-free" eigenstates of spin-1/2 Richardson-Gaudin integrable models
Alexandre Faribault, Claude Dimo
In this work we construct the eigenstates of the most general spin-1/2 Richardson-Gaudin model integrable in an external magnetic field. This includes the possibility for fully ani…
Integrable spin-1/2 Richardson-Gaudin XYZ models in an arbitrary magnetic field
Pieter W. Claeys, Claude Dimo, Stijn De Baerdemacker +1
We establish the most general class of spin-1/2 integrable Richardson-Gaudin models including an arbitrary magnetic field, returning a fully anisotropic (XYZ) model. The restrictio…
Quadratic operator relations and Bethe equations for spin-1/2 Richardson-Gaudin models
Claude Dimo, Alexandre Faribault
In this work we demonstrate how one can, in a generic approach, derive a set of simple quadratic Bethe equations for integrable Richardson-Gaudin (RG) models built out of s…
Ground state solutions of inhomogeneous Bethe equations
S. Belliard, A. Faribault
The distribution of Bethe roots, solution of the inhomogeneous Bethe equations, which characterize the ground state of the periodic XXX Heisenberg spin- chain is inves…
