In this work, we study the magnetic impurity resonance states in the superconducting phase of 'magic' angle twisted bilayer graphene for different pairing symmetries. Using a two-orbital model on the emergent honeycomb lattice, we find that the resonance states are dramatically different for [Formula: see text]-wave pairing and topological nontrivial pairings. When the magnetic impurity is located at one site of the emergent honeycomb lattice, i.e. the center of the AB spot of the moiré pattern…

Topology-Bounded Superfluid Weight in Twisted Bilayer Graphene.
TLDR
The superfluid weight (phase stiffness) of the TBLG superconducting flat bands with a uniform pairing is derived and expressed as an integral of the Fubini-Study metric of the flat bands, and it is shown that the metric integral is lower bounded by the topological C_{2z}T Wilson loop winding number of T BLG flat bands.
