In-plane critical magnetic fields in magic-angle twisted trilayer graphene

Abstract

It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields that are well in excess of the Pauli limit, and much stronger than the in-plane critical magnetic fields of magic-angle twisted bilayer graphene. The difference is surprising because twisted bilayers and trilayers both support the magic-angle flat bands thought to be the fountainhead of twisted graphene superconductivity. We show here that the difference in critical magnetic fields can be traced to a ${\mathcal{C}}_2{\mathcal{M}}_h$ symmetry in trilayers that survives in-plane magnetic fields, and also relative displacements between top and bottom layers that are not under experimental control at present. An gate electric field breaks the ${\mathcal{C}}_2{\mathcal{M}}_h$ symmetry and therefore limits the in-plane critical magnetic field.
