Anisotropic longitudinal optical conductivities of tilted Dirac bands in 1T${}^{\prime }$-MoS${}_2$

Chao-Yang Tan, Chang-Xu Yan, Yong-Hong Zhao +2

1T${}^{\prime }$-MoS${}_2$ exhibits valley-spin-polarized tilted Dirac bands in the presence of external vertical electric field and undergoes a topological phase transition between the t…
