Multifractality in the interacting disordered Tavis-Cummings model

F Mattiotti, J Dubail, D Hagenmüller, J Schachenmayer… - Physical Review B, 2024‏ - APS
We analyze the spectral and transport properties of the interacting disordered Tavis-
Cummings model at half excitation filling. We demonstrate that a Poissonian-level statistics …

Integrable spin- Richardson–Gaudin XYZ models in an arbitrary magnetic field

PW Claeys, C Dimo, S De Baerdemacker… - Journal of Physics A …, 2019‏ - iopscience.iop.org
We establish the most general class of spin-integrable Richardson–Gaudin models
including an arbitrary magnetic field, returning a fully anisotropic (XYZ) model. The …

Thermodynamic limit of the XXZ central spin model with an arbitrary central magnetic field

FK Wen, K Hao - Chinese Physics B, 2023‏ - iopscience.iop.org
The U (1) symmetry of the XXZ central spin model with an arbitrary central magnetic field B is
broken, since its total spin in the z-direction is not conserved. We obtain the exact solutions …
