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…
