Revealing spinons by proximity effect
Antonio Maria Tagliente, Carlos Mejuto-Zaera, Michele Fabrizio
The ghost-Gutzwiller variational wavefunction within the Gutzwiller approximation is shown to stabilize a genuine paramagnetic Mott insulator in the half-filled single-band Hubbard…
Fermi-liquid corrections to the intrinsic anomalous Hall conductivity of topological metals
Ivan Pasqua, Michele Fabrizio
We show that topological metals lacking time-reversal symmetry have an intrinsic non-quantized component of the anomalous Hall conductivity which is contributed not only by the Ber…
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…
Insulating and metallic phases in the one-dimensional Hubbard-Su-Schrieffer-Heeger model: Insights from a backflow-inspired variational wave function
Davide Piccioni, Francesco Ferrari, Michele Fabrizio +1
The interplay between electron-electron and electron-phonon interactions is studied in a one-dimensional lattice model, by means of a variational Monte Carlo method based on genera…
Electrical Transport in the Hatsugai-Kohmoto Model
Daniele Guerci, Giorgio Sangiovanni, Andrew J. Millis +1
We show that in models with the Hatsugai-Kohmoto type of interaction that is local in momentum space thus infinite-range in real space, Kubo formulas neither reproduce the correct…
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…
