Pairing of spinless fermions in two dimensions.
We study the real-space pairing instability of spinless fermions on a two-dimensional square lattice with short-range attractive interactions. Various symmetries of the pairing order parameter are considered. It is found that in both nonflux and flux phases the most stable pairing state is chiral an...
