摘要

我们研究了热力学极限下的(对偶)折叠自旋1/2 XXZ模型。我们特别关注一类包含吉布斯综的局部宏观状态。我们建立了一个热力学Bethe Ansatz描述，并在主导阶上得到了广义的流体力学。值得注意的是，在弹道标度极限下，两个局部宏观状态的连接处会导致基本上任何局部可观察到的轮廓的不连续。

The folded spin-1/2 XXZ model: II. Thermodynamics and hydrodynamics with a minimal set of charges

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.
