Quantum precision measurement of two-dimensional forces with -Newton stability
Xinxin Guo, Zhongcheng Yu, Fansu Wei +5
High-precision sensing of vectorial forces has broad impact on both fundamental research and technological applications such as the examination of vacuum fluctuations \cite{casimir…
The dominant scattering channel induced by two-body collision of D-band atoms in triangular optical lattice
Xinxin Guo, Zhongcheng Yu, Peng Peng +4
The mechanism of atomic collisions in excited bands plays an important role in the study of the orbital physics in optical lattices and simulation of condensed matter physics. Atom…
Evidence of Potts-Nematic Superfluidity in a Hexagonal Optical Lattice
Shengjie Jin, Wenjun Zhang, Xinxin Guo +3
As in between liquid and crystal phases lies a nematic liquid crystal, which breaks rotation with preservation of translation symmetry, there is a nematic superfluid phase bridging…
Asymmetric population of momentum distribution by quasi-periodically driving a triangular optical lattice
Xinxin Guo, Wenjun Zhang, Zhihan Li +3
Ultracold atoms in periodical driven optical lattices enable us to investigate novel band structures and explore the topology of the bands. In this work, we investigate the impact…
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-…
