Probing Loop Currents and Collective Modes of Charge Density Waves in Kagome Materials with NV Centers
Ying-Ming Xie, Naoto Nagaosa
Recently, the unconventional charge density wave (CDW) order with loop currents has attracted considerable attention in the Kagome material family AVSb (A = K, Rb, Cs). How…

Quasi-one-dimensional Supersolids in Luther-Emery Liquids
Ying-Ming Xie, Naoto Nagaosa
The supersolid is a long-sought phase in condensed matter physics, characterized by the coexistence of density wave and superfluid orders. This phase is counterintuitive, as differ…
