Scaling approach to tight-binding transport in realistic graphene devices: the case of transverse magnetic focusing
M. Beconcini, S. Valentini, R. Krishna Kumar +5
Ultra-clean graphene sheets encapsulated between hexagonal boron nitride crystals host two-dimensional electron systems in which low-temperature transport is solely limited by the…
Finite-frequency noise in a topological superconducting wire
Stefano Valentini, Michele Governale, Rosario Fazio +1
In this paper we study the finite-frequency current cross-correlations for a topological superconducting nanowire attached to two terminals at one of its ends. Using an analytic 1D…
A magnetic thermal switch for heat management at the nanoscale
Riccardo Bosisio, Stefano Valentini, Francesco Mazza +4
In a multi-terminal setup, when time-reversal symmetry is broken by a magnetic field, the heat flows can be managed by designing a device with programmable Boolean behavior. We sho…
Separation of heat and charge currents for boosted thermoelectric conversion
Francesco Mazza, Stefano Valentini, Riccardo Bosisio +4
In a multi-terminal device the (electronic) heat and charge currents can follow different paths. In this paper we introduce and analyse a class of multi-terminal devices where this…
Thermopower of three-terminal topological superconducting systems
Stefano Valentini, Rosario Fazio, Vittorio Giovannetti +1
We study the thermopower of a three-terminal setup composed of a quantum dot attached to three electrodes, one of which is a topological superconductor. In the model, superconducti…
Andreev levels spectroscopy of topological three-terminal junctions
Stefano Valentini, Rosario Fazio, Fabio Taddei
We calculate the differential conductance at a probe inserted in the weak link of a topological Josephson junction, consisting of a semiconducting nanowire deposited on top of two…
