Photon-assisted tunneling resonantly controlling spin current of a spin-orbit-coupled atom in a toroidal trap
Zhiqiang Li, Xiaoxiao Hu, Zhao-Yun Zeng +2
The periodic flashing potential has proven to be a powerful tool for investigating directed atomic currents. By applying the flashing ring-shaped potential to spin-orbit (SO) coupl…

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…
