Functional Integral approach to time-dependent heat exchange in open quantum systems: general method and applications
M. Carrega, P. Solinas, A. Braggio +2
We establish the path integral approach for the time-dependent heat exchange of an externally driven quantum system coupled to a thermal reservoir. We derive the relevant influence…
Current enhancement through a time dependent constriction in fractional topological insulators
Giacomo Dolcetto, Luca Vannucci, Alessandro Braggio +2
We analyze the backscattering current induced by a time dependent constriction as a tool to probe fractional topological insulators. We demonstrate an enhancement of the total curr…
Tunneling between helical edge states through extended contacts
G. Dolcetto, S. Barbarino, D. Ferraro +2
We consider a quantum spin Hall system in a two-terminal setup, with an extended tunneling contact connecting upper and lower edges. We analyze the effects of this geometry on the…
Charge tunneling in fractional edge channels
Dario Ferraro, Alessandro Braggio, Nicodemo Magnoli +1
We explain recent experimental observations on effective charge of edge states tunneling through a quantum point contact in the weak backscattering regime. We focus on the behavior…
