Abstract In this paper, we study the influence of periodically driven circularly polarized light on the band structure and transport properties of borophene at high frequency limit. We predict the topological phase transition of borophene from Dirac semimetal to Floquet topological insulator under circularly polarized light by analyzing the anomalous Hall conductance and Chern number. Moreover, due to the inversion asymmetric of borophene, we find a significant nonlinear Hall signal near the tilted Dirac cone and compute the dipole moment of Berry curvature. Our results provide a new method to study the transport properties of borophene.

硼烯中的光致反常霍尔效应和非线性霍尔效应

摘要 在本文中，我们研究了周期性驱动的圆偏振光在高频极限下对硼烯的能带结构和输运特性的影响。我们通过分析异常霍尔电导和陈数来预测圆偏振光下硼烯从狄拉克半金属到 Floquet 拓扑绝缘体的拓扑相变。此外，由于硼烯的反演不对称，我们在倾斜的狄拉克锥附近发现了显着的非线性霍尔信号，并计算了贝里曲率的偶极矩。我们的研究结果为研究硼烯的传输特性提供了一种新方法。
