Signature of phase transitions in the disordered quantum spin Hall state from the entanglement spectrum
Signature of phase transitions in the disordered quantum spin Hall state from the entanglement spectrum
Of the available classes of insulators which have been shown to contain topologically nontrivial properties, one of the most important is class AII, which contains systems that possess time-reversal symmetry $T$ with ${T}^{2}=\ensuremath{-}1.$ This class has been the subject of significant attention as it encompasses nontrivial ${Z}_{2}$ topological insulators such …
