论文摘要
我们在有限掺杂时计算了I型I型和II型多线半学（M-WSM）的光导率（M-WSM）。发现纵向和霍尔电导率均通过垂直于Weyl节点分离的j（单极电荷）重新归一化，并且沿节点沿纵向电导率的纵向电导率对J.薄膜和散装中的Kerr旋转对系统参数的依赖性不同。超薄膜中的Kerr旋转与单极电荷J无关，仅取决于费米速度V f，而大量依赖于单极电荷J，Fermi速度和材料参数。
We calculate the optical conductivity of type-I and type-II multi-Weyl semimetals(m-WSMs) in time-reversal(TR) broken case at finite doping. It is found that both longitudinal and Hall conductivities are renormalized by J(monopole charge) perpendicular to Weyl nodes separation and longitudal conductivity along nodes has non-trivial dependence on J. The Kerr rotations in thin films and bulk have different dependence on system parameters. The Kerr rotation in ultra-thin films is independent of monopole charge J and depends only on Fermi velocity v F while in bulk it dependent on monopole charge J, Fermi velocity and material parameters.
