Abstract: We study the zero-temperature phase diagram of a two dimensional square lattice loaded by spinless fermions, with nearest neighbor hopping and algebraically decaying pairing. We find that for sufficiently long-range pairing, new phases, not continuously… read more here.

Abstract: In this work, we first formulate an effective theory, which generally captures long-range proximity effects of a surface system weakly coupled to an $s$-wave superconductor. The long-range proximity effects include both the emergent long-range pairing… read more here.
