Fluctuation-based evidence for number--phase dynamics in a frustrated orbital superfluid
Rui-Lang Zeng, Zi-Yao Zhang, Ling-Na Wu +5
Frustrated quantum matter can host intertwined orders rooted in symmetry-related low-energy landscapes, yet static order parameters alone do not reveal how fluctuations are organiz…

Observation of Brownian Motion of a Bose-Einstein Condensate
Xiao-Qiong Wang, Rui-Lang Zeng, Zi-Yao Zhang +4
We report on the experimental observation of classical Brownian motion in momentum space by a Bose-Einstein condensate (BEC) of Rubidium atoms prepared in a hexagonal optical latti…
