关于电磁边缘模的一点注记
A note on electromagnetic edge modes
摘要：
我们给出了量子自旋液体中电磁边模作为虚自旋子激发的直观识别。根据统计量，这些边缘模式可以有效地描述由$βγ$或$bc$共形场论。作为一个例子，我们展示了如何这样的描述可以调和的差异上的对数系数的纠缠熵的球。并对纠缠熵中引入拓扑项的可能性作了一些评论。
英文摘要：
We give an intuitive identification for the electromagnetic edge modes as virtual spinon excitations in quantum spin liquids. Depending on the statistics, these edge modes could be effectively described by the $βγ$ or $bc$ conformal field theory. As an example, we show how such a description may reconcile the discrepancy on the logarithmic coefficient of the entanglement entropy on a sphere. Also we give some comments on the possibility of a topological term in the entanglement entropy.
