Conductance of quantum spin Hall edge states from first principles: the critical role of magnetic impurities and inter-edge scattering
Luca Vannucci, Thomas Olsen, Kristian S. Thygesen
The outstanding transport properties expected at the edge of two-dimensional time-reversal invariant topological insulators have proven to be challenging to realize experimentally,…
Hong-Ou-Mandel heat noise in the quantum Hall regime
Flavio Ronetti, Luca Vannucci, Dario Ferraro +4
We investigate heat current fluctuations induced by a periodic train of Lorentzian-shaped pulses, carrying an integer number of electronic charges, in a Hong-Ou-Mandel interferomet…
Hong-Ou-Mandel characterization of multiply charged Levitons
D. Ferraro, F. Ronetti, L. Vannucci +5
We review and develop recent results regarding Leviton excitations generated in topological states of matter - such as integer and fractional quantum Hall edge channels - and carry…
Crystallization of Levitons in the fractional quantum Hall regime
Flavio Ronetti, Luca Vannucci, Dario Ferraro +4
Using a periodic train of Lorentzian voltage pulses, which generates soliton-like electronic excitations called Levitons, we investigate the charge density backscattered off a quan…
Photoassisted shot noise spectroscopy at fractional filling factor
Luca Vannucci, Flavio Ronetti, Dario Ferraro +4
We study the photoassisted shot noise generated by a periodic voltage in the fractional quantum Hall regime. Fluctuations of the current are due to the presence of a quantum point…
Minimal excitation states for heat transport in driven quantum Hall systems
Luca Vannucci, Flavio Ronetti, Jérôme Rech +4
We investigate minimal excitation states for heat transport into a fractional quantum Hall system driven out of equilibrium by means of time-periodic voltage pulses. A quantum poin…
Minimal excitations in the fractional quantum Hall regime
J. Rech, D. Ferraro, T. Jonckheere +3
We study the minimal excitations of fractional quantum Hall edges, extending the notion of levitons to interacting systems. Using both perturbative and exact calculations, we show…
Spin-thermoelectric transport induced by interactions and spin-flip processes in two dimensional topological insulators
Flavio Ronetti, Luca Vannucci, Giacomo Dolcetto +2
We consider thermoelectric transport properties of the edge states of a two dimensional topological insulator in a double quantum point contact geometry coupled to two thermally bi…
Interference induced thermoelectric switching and heat rectification in quantum Hall junctions
Luca Vannucci, Flavio Ronetti, Giacomo Dolcetto +2
Interference represents one of the most striking manifestation of quantum physics in low-dimensional systems. Despite evidences of quantum interference in charge transport have bee…
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…
