Artificial graphene: Unconventional superconductivity in a honeycomb superlattice
Tommy Li, Julian Ingham, Harley D. Scammell
Abstract
The authors propose a mechanism for superconductivity due to repulsive interactions in Dirac systems based on interference effects arising from the Berry phase and show that this mechanism can be realized in semiconductor artificial graphene.
