Exciton condensation driven by bound states of Green's functions zeros
Ivan Pasqua, Andrea Blason, Michele Fabrizio
The interaction driven transition between quantum spin-Hall and Mott insulators in the Bernevig, Hughes and Zhang model is studied by dynamical cluster approximation, and found to…
Luttinger surface dominance and Fermi liquid behaviour of topological Kondo insulators SmB and YbB
Andrea Blason, Ivan Pasqua, Michel Ferrero +1
Defying the traditional classification into metals and insulators, several materials simultaneously display metallic thermal properties and insulating electric behaviour, as if the…
Local Kekulé distortion turns twisted bilayer graphene into topological Mott insulators and superconductors
Andrea Blason, Michele Fabrizio
Magic-angle twisted bilayer graphene displays at different fillings of the four flat bands lying around the charge neutrality point a wealth of notable phases that include magnetic…
Exciton topology and condensation in a model quantum spin Hall insulator
A. Blason, M. Fabrizio
We study by a consistent mean-field scheme the role on the single- and two-particle properties of a local electron-electron repulsion in the Bernevig, Hughes and Zhang model of a q…
