Higher-order Van Hove singularity in magic-angle twisted trilayer graphene
Daniele Guerci, Pascal Simon, Christophe Mora
Abstract
The authors use symmetry arguments to show a higher-order Van Hove singularity in mirror-symmetric twisted trilayer graphene, which is tuned by varying the twist angle and a perpendicular electric field by gating.
