Thouless Pumping of Large Chern Numbers in Optical Floquet Quasicrystals
Shien Wan, Zecheng Li, Bo Song
Chern numbers are central to correlated and topological phenomena, yet most topological systems are associated with Chern numbers of order unity. Here we propose a scheme to achiev…
Optical transport of cold atoms to quantum degeneracy
Yanqing Tao, Yufei Wang, Ligeng Yu +1
Efficient transport of cold atoms is essential for continuous operation, enabling applications ranging from atomic lasers to continuously operated qubits. However, deep potentials…
Two-color magneto-optical trapping of ytterbium atoms
Xiao Li, Yufei Wang, Ligeng Yu +1
We report laser cooling and trapping of ytterbium atoms in a two-color magneto-optical trap (MOT). Benefited from both the broad singlet transition ($^1\text{S}_0\rightarrow {}^1\t…
Realizing a spatially correlated lattice interferometer
Peng Peng, Dekai Mao, Yi Liang +4
Atom interferometers provide a powerful tool for measuring physical constants and testifying fundamental physics with unprecedented precision. Conventional atom interferometry focu…
