标题： Finite-time universality in nonequilibrium CFT

摘要： 最近，关于局部Luttinger模型中非平衡初始状态定义的位置依赖温度分布的热输运动力学，给出了显著简单的精确结果。我们提供了这些结果是如何获得的数学细节。我们还提供了一种替代推导方法，仅涉及能量-动量张量的代数关系，在任何单位共形场理论（CFT）中都成立。这建立了一个初始温度分布与CFT中产生的热波传播之间的简单普遍对应关系。我们将这些结果扩展到更大类的非平衡状态。提出这样的普遍CFT关系可以作为基准，以识别其他模型中非普遍的非平衡动力学特性。 显示英文摘要

摘要： Recently, remarkably simple exact results were presented about the dynamics of heat transport in the local Luttinger model for nonequilibrium initial states defined by position-dependent temperature profiles. We present mathematical details on how these results were obtained. We also give an alternative derivation using only algebraic relations involving the energy-momentum tensor which hold true in any unitary conformal field theory (CFT). This establishes a simple universal correspondence between initial temperature profiles and the resulting heat-wave propagation in CFT. We extend these results to larger classes of nonequilibrium states. It is proposed that such universal CFT relations provide benchmarks to identify nonuniversal properties of nonequilibrium dynamics in other models.
