Signatures of a light-induced exciton condensate exhibiting BEC-BCS crossover

Khanh Duy Nguyen, Gabriele Berruto, Yunhe Bai +7

Exciton condensates provide a platform to study quasiparticle pairing, Bose-Einstein condensation-Bardeen-Cooper-Schrieffer (BEC-BCS) crossover, and excitonic topological phenomena…
