Polarized heat current generated by quantum pumping in two-dimensional topological insulators
F. Ronetti, M. Carrega, D. Ferraro +4
We consider transport properties of a two dimensional topological insulator in a double quantum point contact geometry in presence of a time-dependent external field. In the propos…
Non-equilibrium effects on charge and energy partitioning after an interaction quench
Alessio Calzona, Filippo Maria Gambetta, Matteo Carrega +2
Charge and energy fractionalization are among the most intriguing features of interacting onedimensional fermion systems. In this work we determine how these phenomena are modified…
Time-resolved energy dynamics after single electron injection into an interacting helical liquid
Alessio Calzona, Matteo Acciai, Matteo Carrega +2
The possibility to inject a single electron into ballistic conductors is at the basis of the new field of electron quantum optics. Here, we consider a single electron injection int…
Energy exchange in driven open quantum systems at strong coupling
Matteo Carrega, Paolo Solinas, Maura Sassetti +1
The time-dependent energy transfer in a driven quantum system strongly coupled to a heat bath is studied within an influence functional approach. Exact formal expressions for the s…
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…
