We report a systematic uncertainty of for the USTC Sr1 optical lattice clock, achieving accuracy at the level required for the roadmap of the redefinition of t…
Topological Invariants in Nonlinear Thouless Pumping of Solitons
Fei-Fei Wu, Xian-Da Zuo, Qing-Qing Zhu +8
Recent explorations of quantized solitons transport in optical waveguides have thrust nonlinear topological pumping into the spotlight. In this work, we introduce a unified topolog…
Homogeneous fermionic Hubbard gases in a flat-top optical lattice
Yu-Xuan Wang, Hou-Ji Shao, Yan-Song Zhu +6
Fermionic atoms in a large-scale, homogeneous optical lattice provide an ideal quantum simulator for investigating the fermionic Hubbard model, yet achieving this remains challengi…
Feshbach spectroscopy of ultracold mixtures of and atoms
Ke Xie, Xi Li, Yu-Yang Zhou +7
We report on the observation of Feshbach resonances in ultracold - mixtures, where atoms are respectively prepared in their three…
