多边形区域中整数量子Hall态的纠缠熵

Entanglement entropy of integer Quantum Hall states in polygonal domains

Ivan D. Rodriguez, German Sierra

摘要:

对于拓扑项为零的光滑区域,整数量子霍尔态的纠缠熵满足面积定律。本文考虑了面积定律中含有一个只依赖于顶角的常数项的多边形区域,给出了它的一般表达式,并研究了纠缠谱对几何的依赖性,给出了一个简单的物理解释。

英文摘要:

The entanglement entropy of the integer Quantum Hall states satisfies the area law for smooth domains with a vanishing topological term. In this paper we consider polygonal domains for which the area law acquires a constant term that only depends on the angles of the vertices and we give a general expression for it. We study also the dependence of the entanglement spectrum on the geometry and give it a simple physical interpretation.
