Reduced Density Matrices / Static Correlation Functions of Richardson-Gaudin States Without Rapidities
Alexandre Faribault, Claude Dimo, Jean-David Moisset +1
Seniority-zero geminal wavefunctions are known to capture bond-breaking correlation. Among this class of wavefunctions, Richardson-Gaudin states stand out as they are eigenvectors…
Strong-coupling emergence of dark states in XX central spin models
Claude Dimo, Alexandre Faribault
It was recently shown that the XX central spin model is integrable in the presence of a magnetic field perpendicular to the plane in which the coupling exists. A large number of it…
"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…
