自由费米子、KdV荷、广义Gibbs系综、模变换与线缺陷

Free fermions, KdV charges, generalised Gibbs ensembles, modular transforms and line defects

Max Downing, Gerard Watts

AI总结:

本文研究自由费米子GGE的模性质,将其推广至含任意多个守恒荷的情形,并用线缺陷解释模变换乘积公式,同时提出Hamilton量处理方案。

摘要:

本文重新研究单个自由费米子的广义Gibbs系综(GGE)的模性质问题。我们将此前的提议推广到包含任意多个守恒荷的GGE,并以线缺陷对结果给出物理解释。该缺陷描述完美解释了我们此前发现的模变换乘积公式。我们还提出了一种以Hamilton量方法处理线缺陷的方案。

英文摘要:

In this paper we return to the question of the modular properties of a generalised Gibbs ensemble of a single free fermion. We extend our previous proposals to a GGE containing an arbitrary number of conserved charges and provide a physical interpretation of the result in terms of a line defect. The defect description perfectly explains the product formula for the modular transformation we found previously. We also give a proposal for a Hamiltonian approach to the line defect.
