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…

Uhlmann number in translational invariant systems
Luca Leonforte, Davide Valenti, Bernardo Spagnolo +1
We define the Uhlmann number as an extension of the Chern number, and we use this quantity to describe the topology of 2D translational invariant Fermionic systems at finite temper…
