Description
Summary:In this paper, we study transport properties of the  point in the Brillouin zone of the topological Kondo insulator SmB6 under the application of a circularly polarized light. The transport properties at high-frequency regime and lowfrequency regime as a function of the ratio（κ） of the Dresselhaus-like and Rashba-like spin–orbit parameter are studied based on the Floquet theory and Boltzmann equation respectively. The sign of Hall conductivity at high-frequency regime can be reversed by the ratio κ and the amplitude of the light. The amplitude of the current can be enhanced by the ratio κ.Our findings provide a way to control the transport properties of the Dirac materials at low-frequency regime.
