旋光腔中的真空反常霍尔效应

Vacuum anomalous Hall effect in gyrotropic cavity

Ilya Tokatly, Dmitry Gulevich, Ivan Iorsh

摘要:

本文研究了量子旋光腔中电子气的基态。我们表明,光-物质相互作用导致一个非平凡的拓扑结构的多体电子-光子波函数的特征在于一个非零的Berry曲率。物理上,后者表现为反常霍尔效应、平衡边缘/表面电流的出现和真空涨落引起的轨道磁化。值得注意的是,封闭的异常霍尔电导率和宏观磁化强度的解析表达式得到的相互作用多体的情况下。

英文摘要:

We consider the ground state of an electron gas embedded in a quantum gyrotropic cavity. We show that the light-matter interaction leads to a nontrivial topology of the many-body electron-photon wave function characterized by a nonzero Berry curvature. Physically, the latter manifests as the anomalous Hall effect, appearance of equilibrium edge/surface currents and orbital magnetization induced by vacuum fluctuations. Remarkably, closed analytical expressions for the anomalous Hall conductivity and macroscopic magnetization are obtained for the interacting many-body case.
