Current mean values in the XYZ model

Statistical Mechanics 2023-06-14 v2 Exactly Solvable and Integrable Systems

Abstract

The XYZ model is an integrable spin chain which has an infinite set of conserved charges, but it lacks a global U(1)U(1)-symmetry. We consider the current operators, which describe the flow of the conserved quantities in this model. We derive an exact result for the current mean values, valid for any eigenstate in a finite volume with periodic boundary conditions. This result can serve as a basis for studying the transport properties of this model within Generalized Hydrodynamics.
