Universal symmetry-protected topological invariants for symmetry-protected topological states
Symmetry-protected topological (SPT) states are short-range entangled states with a symmetry G. They belong to a new class of quantum states of matter which are classified by the group cohomology H[superscript d+1](G,R/Z) in d-dimensional space. In this paper, we propose a class of symmetry-protecte...
