Scattering of spinon excitations by potentials in the 1D Heisenberg model
A. Pavlis, X. Zotos
By a semi-analytical Bethe ansatz method and a T-matrix approach we study the scattering of a spinon, the elementary quantum many-body topological excitation in the 1D Heisenberg m…

Dressed excitations, thermodynamics and relaxation in the 1D XXZ Heisenberg model
A. Pavlis, X. Zotos
In this note, we discuss the low and high temperature contribution of Thermodynamic Bethe Ansatz (TBA) dressed excitations in the thermodynamics and energy-magnetization relaxation…
