报告内容:
Floquet engineering (i.e., periodic driving) provides a wide range of pathways to manipulate topological states, leading to emergent nonequilibrium phases that are otherwise not possible in equilibrium cases. Up to now, the attempts of Floquet engineering studied so far have mainly focused on theoretical models, and realistic materials that can realize these proposals are largely unexplored. Here, based on effective models and first-principles calculations, we share our recent work on achieving light-induced topological states (such as quantum anomalous Hall effect, higher-order topological insulators) with novel mechanisms and further towards realizing these topological states in realistic materials.
