Cooperative scattering measurement of coherence in a spatially modulated Bose gas
Bo Lu, Thibault Vogt, Xinxing Liu +3
Correlations of a Bose gas released from an optical lattice are measured using superradiant scattering. Conditions are chosen so that after initial incident light pumping at the Br…
Exploring multi-band excitations of interacting Bose gases in a 1D optical lattice by coherent scattering
Xinxing Liu, Xiaoji Zhou, Wei Zhang +4
We use a coherent Bragg diffraction method to impart an external momentum to ultracold bosonic atoms trapped in a one-dimensional optical lattice. This method is based on the appli…
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…
Mode competition in superradiant scattering of matter waves
Thibault Vogt, Bo Lu, XinXing Liu +3
Superradiant Rayleigh scattering in a Bose gas released from an optical lattice is analyzed with incident light pumping at the Bragg angle for resonant light diffraction. We show c…
Laser driving of Superradiant scattering at variable incidence angle
Bo Lu, Xiaoji Zhou, Thibault Vogt +2
We study superradiant scattering from a Bose-Einstein condensate using a pump laser incident at variable angle and show the presence of asymmetrically populated scattering modes. E…
Rapid non-adiabatic loading in an optical lattice
Xinxing Liu, Xiaoji Zhou, Wei Xiong +2
We present a scheme for non-adiabatically loading a Bose-Einstein condensate into the ground state of a one dimensional optical lattice within a few tens of microseconds typically,…
