Higher-order entanglement and many-body invariants for higher-order topological phases
We discuss how strongly interacting higher-order symmetry protected topological (HOSPT) phases can be characterized from the entanglement perspective: First, we introduce a topological many-body invariant which reveals the noncommutative algebra between a flux operator and C_{n} rotations. We argue...
