A zero-dead-time strontium lattice clock with a stability at level
Xiao-Yong Liu, Peng Liu, Jie Li +20
Optical atomic clocks play a crucial role in fundamental physics, relativistic geodesy, and the future redefinition of the SI second. Standard operation relies on cyclic interrogat…

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…
