Locality-Induced Hierarchical Backflow Wavefunctions for Correlated Fermions
Yu-Tong Zhou, Zheng-Wei Zhou, Wen-Yuan Liu
We show that locality provides a natural principle to hierarchically organize backflow wavefunctions. This leads us to propose a family of variational fermionic states, termed hier…
Topological Anderson Random Laser
Hang-Zheng Shen, Xian-Hao Wei, Xi-Wang Luo +1
Topological lasers and random lasers embody two contrasting strategies for disorder management in photonics: the former suppresses disorder via protected edge transport, while the…
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)…
Super-Heisenberg scaling in a triple point criticality
Jia-Ming Cheng, Yong-Chang Zhang, Xiang-Fa Zhou +1
We investigate quantum-enhanced metrology in a triple point criticality and discover that quantum criticality can not always enhance measuring precision. We have developed suitable…
