Strongly coupled magneto-exciton condensates in large-angle twisted double bilayer graphene
Qingxin Li, Yiwei Chen, LingNan Wei +15
Excitons, the bosonic quasiparticle emerging from Coulomb interaction between electrons and holes, will undergo a Bose-Einstein condensation(BEC) and transition into a superfluid s…
