Diagnosing Floquet Chern and anomalous topological insulators based on Bloch oscillations
Maowu Zuo, Yongguan Ke, Zhoutao Lei +1
It is challenging to distinguish Floquet Chern insulator (FCI) and Floquet anomalous topological insulator (FATI) because of their common features of chiral edge states and far awa…
Topological inverse band theory in waveguide quantum electrodynamics
Yongguan Ke, Jiaxuan Huang, Wenjie Liu +2
Topological phases play a crucial role in the fundamental physics of light-matter interaction and emerging applications of quantum technologies. However, the topological band theor…
Asymmetric topological pumping in nonparaxial photonics
Qingqing Cheng, Huaiqiang Wang, Yongguan Ke +5
Topological photonics was initially inspired by the quantum-optical analogy between the Schrödinger equation for an electron wavefunction and the paraxial equation for a light beam…
Topological Floquet edge states in periodically curved waveguides
Bo Zhu, Honghua Zhong, Yongguan Ke +4
We study the Floquet edge states in arrays of periodically curved optical waveguides described by the modulated Su-Schrieffer-Heeger model. Beyond the bulk-edge correspondence, our…
