Selective high-order topological states and tunable chiral emission in atomic metasurfaces
Yi-Xin Wang, Yan Zhang, Lei Du +2
Atomic metasurfaces (AMs) provide a powerful nanophotonic platform for integrating topological effects into quantum many-body systems. In this Letter, we investigate the quantum op…

Chiral phase modulation and tunable broadband perfect absorber using the coherent cold atomic ensemble
Yi-Xin Wang, Yan Zhang, Lei Du +1
We investigate the two-channel nonreciprocal scattering of a coherent atomic ensemble under the linear spatial Kramers-Kronig modulation, which has potential applications in chiral…

Giant Emitters in a Structured Bath with Non-Hermitian Skin Effect
Lei Du, Lingzhen Guo, Yan Zhang +1
Giant emitters derive their name from nonlocal field-emitter interactions and feature diverse self-interference effects. Most of the existing works on giant emitters have considere…
