受最近实验实现的扭曲过渡金属双硫属化合物双层膜的启发，作者研究了不同形式的单色光对这种材料的影响。他们认为辐射与圆偏振光在自由空间和纵向光，如一个来自波导的TM模式。与辐照的扭曲双层石墨烯不同，他们发现纵向光对材料有更有趣的影响，并诱导拓扑转变。
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.
