Drag-induced skin effect in a Bose-Fermi mixture
Wenjie Liu, Ching Hua Lee, Yi Qin
The non-Hermitian skin effect (NHSE) represents one of the most distinctive phenomena in non-Hermitian physics. Here, we uncover a new drag-induced NHSE mechanism in interacting Bo…

Occupation-selective topological pumping from Floquet gauge fields
Wenjie Liu, Ching Hua Lee, Zhoutao Lei
Topological pumping is conventionally governed by single-particle band topology. Here we show that promoting tunneling to a dynamical, occupation-conditioned variable fundamentally…

Localization and scattering of a photon in quasiperiodic qubit arrays
Xinyin Zhang, Yongguan Ke, Zhengzhi Peng +4
We study the localization and scattering of a single photon in a waveguide coupled to qubit arrays with quasiperiodic spacings. As the quasiperiodic strength increases, localized s…
