Matrix product states and equivariant topological field theories for bosonic symmetry-protected topological phases in (1+1) dimensions
Abstract Matrix Product States (MPSs) provide a powerful framework to study and classify gapped quantum phases — symmetry-protected topological (SPT) phases in particular — defined in one dimensional lattices. On the other hand, it is natural to expect that gapped quantum phases in the limit of zero...
