A discriminating string order parameter for topological phases of gapped SU(N) spin chains
Kasper Duivenvoorden, Thomas Quella
One-dimensional gapped spin chains with symmetry PSU(N) = SU(N)/Z_N are known to possess N different topological phases. In this paper, we introduce a non-local string order parame…

On topological phases of spin chains
Kasper Duivenvoorden, Thomas Quella
Symmetry protected topological phases of one-dimensional spin systems have been classified using group cohomology. In this paper, we revisit this problem for general spin chains wh…
