Dimension Crossing Turbulent Cascade in an Excited Lattice Bose Gas
Tianwei Zhou, Ruixiao Yao, Kaixiang Yang +7
Turbulence is an intriguing non-equilibrium state, which originates from fluid mechanics and has far-reaching consequences in the description of climate physics, the characterizati…
Observation of atom-number fluctuations in optical lattices via quantum collapse and revival dynamics
Tianwei Zhou, Kaixiang Yang, Zijie Zhu +9
Using the quantum collapse and revival phenomenon of a Bose--Einstein condensate in three-dimensional optical lattices, the atom number statistics on each lattice site are experime…
Bogoliubov-Cherenkov Radiation in an Atom Laser
B. M. Henson, Xuguang Yue, S. S. Hodgman +5
We develop a simple yet powerful technique to study Bogoliubov-Cherenkov radiation by producing a pulsed atom laser from a strongly confined Bose-Einstein condensate. Such radiatio…
Matter wave interference of dilute Bose gases in the critical regime
Xuguang Yue, Shujuan Liu, Biao Wu +1
Ultra-cold atomic gases provide new chance to study the universal critical behavior of phase transition. We study theoretically the matter wave interference for ultra-cold Bose gas…
Interference effect of critical ultra-cold atomic Bose gases
Xuguang Yue, Shujuan Liu, Hongwei Xiong
For ultra-cold atomic gases close to the critical temperature, there is a divergent correlation behavior within the critical regime. This divergent correlation behavior is the corn…

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…

We propose and demonstrate a momentum filter for atomic gas based on a designed Talbot-Lau interferometer. It consists in two identical optical standing wave pulses separated by a…
Critical correlations in an ultracold Bose gas revealed by means of a temporal Talbot-Lau interferometer
Wei Xiong, Xiaoji Zhou, Xuguang Yue +3
We study experimentally the critical correlation in an ultra-cold Bose gas with a temporal Talbot-Lau (TL) interferometer. Near the critical temperature, we observe a bi-modal dens…
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…
