Classification of symmetry-protected phases for interacting fermions in two dimensions
Recently, it has been established that two-dimensional bosonic symmetry-protected topological (SPT) phases with on-site unitary symmetry G can be completely classified by the group cohomology H[superscript 3](G,U(1)). Later, group supercohomology was proposed as a partial classification for SPT phas...
