Chiral Topological Superconductors Enhanced by Long-Range Interactions
We study the phase diagram and edge states of a two-dimensional $p$-wave superconductor with long-range hopping and pairing amplitudes. New topological phases and quasiparticles different from the usual short-range model are obtained. When both hopping and pairing terms decay with the same exponent, one of the topological chiral phases with …
