Geometric contributions to the superfluid weight. a Schematics of a double layer formed by two TBGs in which an EC state is expected to form when the chemical potential in the top layer μT is equal and opposite to the chemical potential in the bottom layer μB. b Dependence on twist angle of the conventional and geometric contributions to the superfluid weight Ds of an EC formed in a double TBG, for fixed chemical potential μ ≡ μT = −μB = 0.2 mev. c, d Dependence on μ, for different twist angles, of conventional and geometric contributions, respectively, to Ds. Adapted from ref. 154.
