The folded spin-1/2 XXZ model: II. Thermodynamics and hydrodynamics with a minimal set of charges
Lenart Zadnik, Kemal Bidzhiev, Maurizio Fagotti
Abstract
We study the (dual) folded spin-1/2 XXZ model in the thermodynamic limit. We focus, in particular, on a class of ``local'' macrostates that includes Gibbs ensembles. We develop a thermodynamic Bethe Ansatz description and work out generalised hydrodynamics at the leading order. Remarkably, in the ballistic scaling limit the junction of two local macrostates results in a discontinuity in the profile of essentially any local observable.
