DOI: 10.1038/nphys4116
Abstract: An electronic double layer, subjected to a high magnetic field, can form an exciton condensate: a Bose–Einstein condensate of Coulomb-bound electron–hole pairs. Now, exciton condensation is reported for a graphene/boron-nitride/graphene structure. read more here.

DOI: 10.1103/physrevb.105.l140506
Abstract: Flat-band systems are a promising platform for realizing exotic collective ground states with spontaneously broken symmetry because the electron-electron interactions dominate the kinetic energy. A state of particular interest would be the chased after interlayer-phase-coherent… read more here.

Abstract: The bulk properties of the bilayer quantum Hall state at total filling factor one have been intensively studied in experiment. Correlation induced phenomena such as Josephson-like tunneling and zero Hall resistance have been reported. In… read more here.
