Projective construction of two-dimensional symmetry-protected topological phases with U(1), SO(3), or SU(2) symmetries
We propose a general approach to construct symmetry protected topological (SPT) states (i.e., the short-range entangled states with symmetry) in 2D spin/boson systems on lattice. In our approach, we fractionalize spins/bosons into different fermions, which occupy nontrivial Chern bands. After the Gu...
