Flow-polarity decoupling and universal mobility enhancement in dense bacterial active fluids with mesoscale order
Yuhao Wang, Premkumar Leishangthem, Yiming Ding +2
Active fluids consisting of living cells or synthetic microswimmers display rich emergent behavior and nonequilibrium mechanical properties, which not only shed light on various bi…

Topology-Enabled Switchable Unidirectional Radiative Band in a Bilayer Photonic Crystal
Zhiyi Yuan, Vytautas Valuckas, Yuhao Wang +6
Controlling how an open photonic system exchanges energy with its environment-and in particular how it radiates into the far field-is a cornerstone of non-Hermitian wave physics an…

Hybridization of Non-Hermitian Topological Interface Modes
Yuhao Wang, Hai-Chau Nguyen, Zhiyi Yuan +5
We propose and experimentally demonstrate the hybridization of radiating topological interface states, analogous to Jackiw-Rebbi states but in gain media with radiation fields. Thi…
