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-…
