A Connectivity-Order Law and Conditional Minimal-Mechanism Identification in Many-Body Geometric Phases
Kuo Hai, Junhao Huang, Qiong Chen +1
The value of a multiqubit geometric phase at a single operating point does not reveal whether it was generated directly or through a connected sequence of lower-body interactions.…
Exact solutions for a spin-orbit coupled bosonic double-well system
Yunrong Luo, Xuemei Wang, Jia Yi +3
Exact solutions for spin-orbit (SO) coupled cold atomic systems are very important and rare in physics. In this paper, we propose a simple method of combined modulations to generat…

For a Bose-Einstein condensate loaded into a weak traveling optical superlattice it is demonstrated that under a stochastic initial set and in a given parameter region the solitoni…
