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…

Josephson-based threshold detector for Lévy distributed fluctuations

Claudio Guarcello, Davide Valenti, Bernardo Spagnolo +2

We propose a threshold detector for Lévy distributed fluctuations based on a Josephson junction. The Lévy noise current added to a linearly ramped bias current results in clear cha…
