Classifying phases protected by matrix product operator symmetries using matrix product states

Abstract: We classify the different ways in which matrix product states (MPS) can transform under the action of matrix product operator (MPO) symmetries. We give a local characterization of MPS tensors that generate ground spaces which remain invariant under a global MPO symmetry and generally correspond to symmetry breaking phases. This allows us to derive a set of quantities, satisfying the so-called coupled pentagon equations, invariant under continuous deformations of the MPS tensor, which provides the invariants to… Show more
