论文摘要
我们研究了两个空间维度的拓扑排序系统之间的间隙域壁的地面纠缠。我们得出了对基态纠缠熵的通用校正，该熵等于位于域壁上的一组超选择扇区的总量子尺寸的对数。该表达式来自最近提出的纠缠bootstrap方法。
We study the ground-state entanglement of gapped domain walls between topologically ordered systems in two spatial dimensions. We derive a universal correction to the ground-state entanglement entropy, which is equal to the logarithm of the total quantum dimension of a set of superselection sectors localized on the domain wall. This expression is derived from the recently proposed entanglement bootstrap method.
