Dynamical Signatures of Floquet Topology in Wave Packet Dynamics
Xin Shen, Bing Lu, Yan-Qing Zhu
Periodically driven quantum systems, known as Floquet systems, provide a versatile platform for engineering novel topological phases absent in static settings. However, dynamically…

Casimir-Polder interaction between an atom and a Chern insulator: topological signature and long-range repulsion
Bing-Sui Lu
We consider the Casimir-Polder interaction between a two-level atomic system and a Chern insulator for both the resonant and nonresonant channels. For a right circularly polarized…
