Chiral Quantum Transport with Perfect Circulation: From Floquet Engineering toAnyonic Dynamics
Chaorong Guo, Hongzheng Wu, Zenong Zhou +2
Perfect chiral circulation-the sequential transfer of a quantum state around a closed loop with unit fidelity-has been achieved in specific few-site systems, yet the universal phys…

Controlled pumping of matter-wave solitons in a one-dimensional optical superlattice
Xiaoxiao Hu, Zhiqiang Li, Ai-Xi Chen +1
We study the pumping of matter-wave solitons formed in Bose-Einstein condensates (BECs) with attractive atomic interactions that are loaded into optical superlattices in which one…

Chaos signatures of current phase transition in a toroidal trap
Zhiqiang Li, Xiaoxiao Hu, Zhao-Yun Zeng +3
In this work we demonstrate how the directed motion of atomic Bose-Einstein condensates in a toroidal trap can be controlled by applying a zero-mean oscillatory driving field. We s…
