Anomalous wave-packet transport on boundaries of Floquet topological systems
Xin-Xin Yang, Kai-Ye Shi, F. Nur Ünal +1
A two-dimensional periodically driven (Floquet) system with zero winding number in the absence of time-reversal symmetry is usually considered topologically trivial. Here, we study…

Stability of vortices in exciton-polariton condensates with spin-orbital-angular-momentum coupling
Xin-Xin Yang, Wei Zhang, Zhen-Xia Niu
The existence and dynamics of stable quantized vortices is an important subject of quantum many-body physics. Spin-orbital-angular-momentum coupling (SOAMC), a special type of spin…

Superradiant Transition to a Fermionic Quasicrystal in a Cavity
Bo-Hao Wu, Xin-Xin Yang, Wei Zhang +1
Recently, the steady state superradiance in degenerate Fermi gases has been realized in a cavity, following the previous discovery of the Dicke transition in Bose gases. The most p…
