Abstract
Motivated by the recent experimental realization of twisted transition metal dichalcogenide bilayers, the authors study the influence of different forms of monochromatic light on such materials. They consider irradiation with circularly polarized light in free space and longitudinal light, such as the one coming from the waveguide's TM mode. Unlike irradiated twisted bilayer graphene, they find that the longitudinal light has a more interesting effect on the material and induces topological transitions.
