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…
Phase control of localization in the nonlinear two-mode system from harmonic mixing driving: Perturbative analysis and symmetry consideration
Xianchao Le, Zhao-Yun Zeng, Baiyuan Yang +7
In this paper, we present a rigorous analysis of symmetry and underlying physics of the nonlinear two-mode system driven by a harmonic mixing field, by means of multiple scale asym…
Phonon blockade in a nanomechanical resonator resonantly coupled to a qubit
Xun-Wei Xu, Ai-Xi Chen, Yu-xi Liu
We study phonon statistics in a nanomechanical resonator (NAMR) which is resonantly coupled to a qubit. We find that there are two different mechanisms for phonon blockade in such…
Interference-induced enhancement of field entanglement in a microwave-driven V-type single-atom laser
Wen-Xing Yang, Ai-Xi Chen, Ting-Ting Zha +2
We investigate the generation and the evolution of two-mode continuous-variable (CV) entanglement from system of a microwave-driven V-type atom in a quantum beat laser. By taking i…
