Levitons in helical liquids with Rashba spin-orbit coupling probed by a superconducting contact
Flavio Ronetti, Matteo Carrega, Maura Sassetti
We consider transport properties of a single edge of a two-dimensional topological insulators, in presence of Rashba spin-orbit coupling, driven by two external time-dependent volt…
Transport signatures of a Floquet topological transition at the helical edge
C. Fleckenstein, N. Traverso Ziani, L. Privitera +2
The manipulation of the helical edge states of two-dimensional topological insulators is crucial for the development of technological applications. Recently, an important step forw…
Spectral properties of interacting helical channels driven by Lorentzian pulses
Matteo Acciai, Alessio Calzona, Matteo Carrega +2
Precise shaping of coherent electron sources allows the controlled creation of wavepackets into a one dimensional (1D) quantum conductor. Periodic trains of Lorentzian pulses have…
Levitons in superconducting point contacts
Matteo Acciai, Flavio Ronetti, Dario Ferraro +4
We investigate the transport properties of a superconducting quantum point contact in the presence of an arbitrary periodic drive. In particular, we calculate the dc current and no…
Feasible model for photo-induced interband pairing
S. Porta, L. Privitera, N. Traverso Ziani +3
Recently, it has been proposed that a mechanism for the appearance of non-equilibrium superconductivity in a resonantly driven semiconductor with repulsive interband interactions e…
Optimal work-to-work conversion of a nonlinear quantum brownian duet
Matteo Carrega, Maura Sassetti, Ulrich Weiss
Performances of work-to-work conversion are studied for a dissipative nonlinear quantum system with two isochromatic phase-shifted drives. It is shown that for weak Ohmic damping s…
