论文摘要
在本文中，我们研究了圆形极化光的照明下PBC/MNSE异质结构中PBC/MNSE异质结构的拓扑特性和霍尔电导率。在高频制度下，基于浮雕理论和格林的功能形式主义研究了能量差距，雪恩数和霍尔电导率。旋转轨道耦合和光之间的相互作用导致异常霍尔状态和旋转霍尔状态之间的拓扑相变，这与两个虚拟光子的发射和吸收有关。异常的大厅电导率取决于光的极化，而自旋霍尔电导率是独立的。
In this paper, we study topological properties and Hall conductivities in PbC/MnSe heterostructure under the illumination of a circularly polarized light. At high frequency regime, energy gap, Chern numbers, and Hall conductivities are studied based on the Floquet theory and Green's function formalism, respectively. The interplay between spin orbit coupling and light leads to topological phase transition between anomalous Hall states and spin Hall states, which is related to the emission and absorption of two virtual photons. The anomalous Hall conductivities are dependent on polarization of light, while the spin Hall conductivity is independent.
