Gapped quantum phases for the S=1 spin chain with D2h symmetry
We study different quantum phases in integer spin systems with on-site D[subscript 2h]=D[subscript 2]⊗Z[subscript 2] and translation symmetry. We find four distinct nontrivial phases in S=1 spin chains despite the fact that they all have the same symmetry. All four phases have gapped bulk excitation...
