Haldane Model at finite temperature
Luca Leonforte, Davide Valenti, Bernardo Spagnolo +2
We consider the Haldane model, a 2D topological insulator whose phase is defined by the Chern number. We study its phases as temperature varies by means of the Uhlmann number, a fi…

On critical properties of Berry curvature in Kitaev honeycomb model
Francesco Bascone, Luca Leonforte, Davide Valenti +2
We analyse the Kitaev honeycomb model, by means of the Berry curvature with respect to Hamiltonian parameters. We concentrate on the ground-state vortex-free sector, which allows u…
