Atomic Ramsey interferometry with S- and D-band in a triangular optical lattice
Xiangyu Dong, Chengyang Wu, Zhongcheng Yu +5
Ramsey interferometers have wide applications in science and engineering. Compared with the traditional interferometer based on internal states, the interferometer with external qu…
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…
