Observation of quantum dynamical oscillations of ultracold atoms in the F and D bands of an optical lattice
Zhongkai Wang, Baoguo Yang, Dong Hu +4
We report the observation of quantum dynamical oscillations of ultracold atomic gases in the F and D bands of a single-well optical lattice. We are able to control the Bragg reflec…
The observation of diffraction phases in matter wave scattering
Xuguang Yue, Yueyang Zhai, Zhongkai Wang +3
We study the diffraction phase of different orders via the Dyson expansion series, for ultracold atomic gases scattered by a standing-wave pulse. As these diffraction phases are no…
Asymmetric superradiant scattering and abnormal mode amplification induced by atomic density distortion
Zhongkai Wang, Linxiao Niu, Peng Zhang +4
The superradiant Rayleigh scattering using a pump laser incident along the short axis of a Bose-Einstein condensate with a density distortion is studied, where the distortion is fo…
Manipulating the momentum state of a condensate by sequences of standing wave pulses
Wei Xiong, Xuguang Yue, Zhongkai Wang +2
We analyze the effects of sequences of standing wave pulses on a Bose-Einstein condensate (BEC). Experimental observations are in good agreement with a numerical simulation based o…
