Optimized fringe removal algorithm for absorption images
Linxiao Niu, Xinxin Guo, Yuan Zhan +3
Optical absorption imaging is a basic detection technique for obtaining information from matter waves, in which the absorption signal can be obtained by comparing the recorded dete…
Observation of a dynamical sliding phase superfluid with P-band bosons
Linxiao Niu, Shengjie Jin, Xuzong Chen +2
Sliding phases have been long sought after in the context of coupled XY-models, as they are of relevance to various many-body systems such as layered superconductors, freestanding…
Echo-Ramsey Interferometry with Motional Quantum States
D. Hu, L. X. Niu, S. J. Jin +4
Ramsey interferometers (RIs) using internal electronic or nuclear states find wide applications in science and engineering. We develop a matter wave Ramsey interferometer for motio…
Observation of Quantum Equilibration in Dilute Bose Gases
Linxiao Niu, Pengju Tang, Baoguo Yang +3
We investigate experimentally the dynamical relaxation of a non-integrable quantum many-body system to its equilibrium state. A Bose-Einstein condensate is loaded into the first ex…
Long-time nonlinear dynamical evolution for P-band ultracold atoms in an optical lattice
Dong Hu, Linxiao Niu, Baoguo Yang +4
We report the long-time nonlinear dynamical evolution of ultracold atomic gases in the P-band of an optical lattice. A Bose-Einstein condensate (BEC) is fast and efficiently loaded…
Excitation of atoms in an optical lattice driven by polychromatic amplitude modulation
Linxiao Niu, Dong Hu, Shengjie Jin +3
We investigate the mutiphoton process between different Bloch states in an amplitude modulated optical lattice. In the experiment, we perform the modulation with more than one freq…
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…
