Propagating Neutral Modes in an Intervalley Coherent State
Elementary excitations in quantum systems govern their responses to intrinsic and extrinsic stimuli, such as phase stabilities and device operations. Emergent collective …
Optical imaging of flavor order in flat band graphene
We describe an optical technique that sensitively and selectively detects flavor textures via the exciton response of a proximal transition metal dichalcogenide layer (WSe2). …

Tunable transient valley-pseudospin orders in a moiré Bose-Hubbard model
We demonstrate exciton-filling and magnetic field tunable exciton valley-pseudospin orders in a doped correlated insulator of excitons. We find evidence of an in-plane order of …
Correlated insulator of excitons in WSe2/WS2 moiré superlattices
We observed a bosonic correlated insulator in WSe2/WS2 moiré superlattices composed of excitons, tightly bound electron-hole pairs. In our experiment, we built a novel optical …
