Superconductivity in monolayer FeSe enhanced by quantum geometry

We formulate the superfluid weight in unconventional superconductors with k-dependent Cooper pair potentials based on the geometric properties of Bloch electrons. We apply the formula to a model of monolayer FeSe obtained by first-principles calculation. Our numerical calculations point to a signifi...
