Observation of two-component exciton condensates in an excitonic insulator
Ruishi Qi, Qize Li, Jiahui Nie +9
Macroscopic quantum coherence emerges when bosons condense into a Bose-Einstein condensate (BEC). First observed as a single-component superfluid in helium, BECs later emerged in u…

Observation of an exciton crystal in a moiré excitonic insulator
Ruishi Qi, Qize Li, Haleem Kim +9
Strong Coulomb interactions can drive electrons to crystallize into a Wigner lattice. Achieving the bosonic analogue - a crystal of excitons - has remained elusive due to their sho…
