Fluctuations and Correlations of Local Topological Order Parameters in Disordered Two-dimensional Topological Insulators
Roberta Favata, Nicolas Baù, Antimo Marrazzo
Two-dimensional topological insulators are characterized by an insulating bulk and conductive edge states protected by the nontrivial topology of the bulk electronic structure. The…

Interaction-induced phases in the half-filled Bernevig-Hughes-Zhang model in one dimension
Roberta Favata, Davide Piccioni, Alberto Parola +1
We explore the ground-state properties of a one-dimensional model with two orbitals per site, where, in addition to atomic energies , intra- and inter-orbital hoppings, the…

Single-point spin Chern number in a supercell framework
Roberta Favata, Antimo Marrazzo
We present an approach for the calculation of the topological invariant in non-crystalline two-dimensional quantum spin Hall insulators. While topological invariants…
