We identify states favored by Coulomb interactions projected onto the Wannier basis of the
four narrow bands of the “magic angle” twisted bilayer graphene. At the filling of 2 …

Dirac materials

TO Wehling, AM Black-Schaffer… - Advances in Physics, 2014 - Taylor & Francis
A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

Overdo** graphene beyond the van Hove singularity

P Rosenzweig, H Karakachian, D Marchenko… - Physical Review Letters, 2020 - APS
At very high do** levels the van Hove singularity in the π* band of graphene becomes
occupied and exotic ground states possibly emerge, driven by many-body interactions …
