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…
Multi-reservoir enhanced loading of tweezer atom arrays
Xu Yan, Chengdong He, Kai Wen +4
We introduce a species-independent method for improved loading into a single-atom optical tweezer array, utilizing iterative loading with multiple reservoir tweezers. Demonstrated…
Creation of a tweezer array for cold atoms utilizing a generative neural network
Zejian Ren, Xu Yan, Kai Wen +4
Optical tweezers have become essential tools for dynamically manipulating objects, ranging from microspheres or biological molecules to neutral atoms. In this study, we demonstrate…
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…
Collective dipole oscillations of a spin-orbit coupled Fermi gas
Shanchao Zhang, Chengdong He, Elnur Hajiyev +3
The collective dipole mode is induced and measured in a spin-orbit (SO) coupled degenerate Fermi gas of Yb atoms. Using a differential optical Stark shift, we split the deg…
Observation of symmetry-protected topological band with ultracold fermions
Bo Song, Long Zhang, Chengdong He +5
Symmetry plays a fundamental role in understanding complex quantum matter, particularly in classifying topological quantum phases, which have attracted great interests in the recen…
Spin-orbit coupled two-electron Fermi gases of ytterbium atoms
Bo Song, Chengdong He, Shanchao Zhang +4
We demonstrate all-optical implementation of spin-orbit coupling (SOC) in a two-electron Fermi gas of Yb atoms by coupling two hyperfine ground states with a narrow optical…
Atomic Properties of Lu
Eduardo Paez, K. J. Arnold, Elnur Hajiyev +5
Singly ionised Lutetium has recently been suggested as a potential clock candidate. Here we report a joint experimental and theoretical investigation of \ce{Lu^+}. Measurements rel…
Prospects for atomic clocks based on large ion crystals
Kyle Arnold, Elnur Haciyev, Eduardo Paez +3
We investigate the feasibility of precision frequency metrology with large ion crystals. For clock candidates with a negative differential static polarisability, we show that micro…
A high flux source of cold strontium atoms
T. Yang, K. Pandey, M. S. Pramod +6
We describe an experimental apparatus capable of achieving a high loading rate of strontium atoms in a magneto-optical trap operating in a high vacuum environment. A key innovation…
