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…

Finite temperature geometric properties of the Kitaev honeycomb model
Francesco Bascone, Luca Leonforte, Bernardo Spagnolo +2
We study finite temperature topological phase transitions of the Kitaev's spin honeycomb model in the vortex-free sector with the use of the recently introduced mean Uhlmann curvat…
