In-Plane Critical Magnetic Fields in Magic-Angle Twisted Trilayer Graphene

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