Excitonic density wave and spin-valley superfluid in bilayer transition metal dichalcogenide

A correlated insulator has recently been observed in twisted bilayer WSe2 moiré superlattices. Here, Bi and Fu present a theory and predict the insulating state to be an excitonic density wave as well as a spin-valley superfluid, which can be tested by optical pump-probe experiments.
