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…
Parallel multicomponent interferometer with a spinor Bose-Einstein condensate
Pengju Tang, Peng Peng, Zhihan Li +3
Atom interferometry with high visibility is of high demand for precision measurements. Here, a parallel multicomponent interferometer is achieved by preparing a spin- Bose-Einst…
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…
Extraction and identification of noise patterns for ultracold atoms in an optical lattice
Shuyang Cao, Pengju Tang, Xinxin Guo +3
To extract useful information about quantum effects in cold atom experiments, one central task is to identify the intrinsic quantum fluctuation from extrinsic system noises of vari…
Period-doubled Bloch states in a Bose-Einstein condensate
Baoguo Yang, Pengju Tang, Xinxin Guo +3
We study systematically the period-doubled Bloch states for a weakly interacting Bose-Einstein condensate in a one-dimensional optical lattice. This kind of state is of form $ψ_k=e…
Finite Temperature Phase Transition in a Cross-Dimensional Triangular Lattice
Shengjie Jin, Xinxin Guo, Peng Peng +3
Atomic many-body phase transitions and quantum criticality have recently attracted much attention in non-standard optical lattices. Here we perform an experimental study of finite-…
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…
Relaxation of Bosons in One Dimension and the Onset of Dimensional Crossover
Chen Li, Tianwei Zhou, Igor Mazets +8
We study ultra-cold bosons out of equilibrium in a one-dimensional (1D) setting and probe the breaking of integrability and the resulting relaxation at the onset of the crossover f…
Shortcut loading atoms into an optical lattice
Xiaoji Zhou, Shengjie Jin, J. Schmiedmayer
We present an effective and fast (few microseconds) procedure for transferring ultra-cold atoms from the ground state in a harmonic trap into the desired bands of an optical lattic…
