Bistability and Exact Reflectionless States in Nonlinear Scattering of a Bose--Einstein Condensate
Feilong Wang, Jinlin Fan, Ruolin Chai +2
We investigate the mean-field scattering dynamics of a quasi-one-dimensional Bose--Einstein condensate interacting with a Rosen--Morse potential. For specific potential and nonline…

Photon Routing Induced by Giant Atoms in a Synthetic Frequency Dimension
Ruolin Chai, Guoqing Cai, Qiongtao Xie +2
We propose a hardware-efficient photon routing scheme based on a dynamically modulated multi-mode ring resonator and a driven cyclic three-level artificial atom, which effectively…
