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…

Ferroelectricity in twisted double bilayer graphene
Renjun Du, Jingkuan Xiao, Di Zhang +7
Two-dimensional ferroelectrics can maintain vertical polarization up to room temperature, and are, therefore, promising for next-generation nonvolatile memories. Although natural t…
