Effective statistical fringe removal algorithm for high-sensitivity imaging of ultracold atoms
Bo Song, Chengdong He, Zejian Ren +3
High-sensitivity imaging of ultracold atoms is often challenging when interference patterns are imprinted on the imaging light. Such image noises result in low signal-to-noise rati…
Observation of nodal-line semimetal with ultracold fermions in an optical lattice
Bo Song, Chengdong He, Sen Niu +4
Observation of topological phases beyond two-dimension (2D) has been an open challenge for ultracold atoms. Here, we realize for the first time a 3D spin-orbit coupled nodal-line s…
Apparatus for producing single strontium atoms in an optical tweezer array
Kai Wen, Huijin Chen, Xu Yan +5
We outline an experimental setup for efficiently preparing a tweezer array of Sr atoms. Our setup uses permanent magnets to maintain a steady-state two-dimensional magneto-o…
Observing a topological phase transition with deep neural networks from experimental images of ultracold atoms
Entong Zhao, Ting Hin Mak, Chengdong He +4
Although classifying topological quantum phases have attracted great interests, the absence of local order parameter generically makes it challenging to detect a topological phase…
Heuristic machinery for thermodynamic studies of SU(N) fermions with neural networks
Entong Zhao, Jeongwon Lee, Chengdong He +4
The power of machine learning (ML) provides the possibility of analyzing experimental measurements with an unprecedented sensitivity. However, it still remains challenging to probe…
Thermodynamics of Spin-Imbalanced Fermi Gases with SU(N) Symmetric Interaction
Chengdong He, Xin-Yuan Gao, Ka Kwan Pak +6
Thermodynamics of degenerate Fermi gases has been extensively studied through various aspects such as Pauli blocking effects, collective modes, BCS superfluidity, and more. Despite…
