Topological States Enabled by Non-local Nonlinearity in Synthetic Dimensions
Chong-Xiao Chen, Zheng-Wei Zhou, Han Pu +1
The interplay between topology and nonlinearity represents a central challenge in modern physics. Here, we investigate this interplay by considering a synthetic Su-Schrieffer-Heege…

Dicke materials as a resource for quantum squeezing
Vaibhav Sharma, Shung-An Koh, Jonathan Stepp +8
We study magnetic materials whose low energy physics can be effectively described by a Dicke model, which we term Dicke materials. We show how a Dicke model emerges in such materia…

Nonreciprocal and long-range three-body interactions in Bose-Einstein condensates induced by optical feedback
Yi-Qing Zhang, Liang-Jun He, Han Pu +2
We propose generating long-range and nonreciprocal three-body interactions in quantum gases via optical feedback. By placing a quasi-two-dimensional Bose-Einstein condensate (BEC)…
