Magnetothermal transport in the spin-1/2 easy-axis antiferromagnetic chain
X. Zotos
By an exact analytical approach we study the magnetothermal transport in the spin-1/2 easy-axis Heisenberg model, in particular the thermal conductivity and spin Seebeck effect as…

High temperature dynamics in quantum compass models
A. K. R. Briffa, X. Zotos
We analyze the high temperature spin dynamics of compass models using a moment expansion. We point out that the evaluation of moments maps to the enumeration of paths in a branchin…

A TBA description of thermal transport in the XXZ Heisenberg model
X. Zotos
It is shown that the Bethe ansatz formulation of the easy-plane 1D Heisenberg model thermodynamics (TBA) by Takahashi and Suzuki and the subsequent analysis of the spin Drude weigh…
