Title: Current mean values in the XYZ model
(Submitted on 1 Nov 2022 (v1), last revised 12 Jan 2023 (this version, v2))
Abstract: The XYZ model is an integrable spin chain which has an infinite set of conserved charges, but it lacks a global $U(1)$-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.
