15 Apr 2020 | | Abstract: | We introduce a characterization of topological order based on bulk
oscillations of the entanglement entropy and the definition of an ’entanglement
gap’, showing that it is generally applicable to pure and disordered quantum
systems. Using exact diagonalization and the strong disorder renormalization
group method, we demonstrate that this approach gives results in agreement with
the use of traditional topological invariants, especially in cases where
topological order is known to persist in the presence of off-diagonal bond
disorder. The entanglement gap is then used to analyze classes of quantum
systems with alternating bond types, allowing us to construct their topological
phase diagrams. The validity of these phase diagrams is verified in limiting
cases of dominant bond types, where the solution is known. | | Source: | arXiv, 2004.7186 | | Services: | Forum | Review | PDF | Favorites | |
