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…

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…
