We consider an interacting quantum dot working as a coherent source of single electrons. The dot is tunnel coupled to a reservoir and capacitively coupled to a gate terminal with an applied ac potential. At low frequencies, this is the quantum analog of the $RC$ circuit with a purely dynamical response. We investigate the quantized dynamics as a consequence of ac pulses with large amplitude. Within a Keldysh-Green function formalism we derive the time-dependent current in the Coulomb blockade…

Nonlinear electric response of chiral topological superconductors
We investigate, in the non-equilibrium Keldysh frame, a topological resistor–capacitor (RC) circuit consisting of a quantum dot coupled to a Majorana edge mode formed around a chiral topological
Work exchange, geometric magnetization, and fluctuation-dissipation relations in a quantum dot under adiabatic magnetoelectric driving
We study the adiabatic dynamics of the charge, spin and energy of a quantum dot with a Coulomb interaction under two-parameter driving, associated to time-dependent gate voltage and magnetic field.
Cavity QED with hybrid nanocircuits: from atomic-like physics to condensed matter phenomena
This work presents the experimental state of the art of mesoscopic QED and its theoretical description, and uses cavity photons to reveal the dynamics of electron tunneling between a nanoconductor and fermionic reservoirs.
Phase-Coherent Dynamics of Quantum Devices with Local Interactions
This review illustrates how Local Fermi Liquid (LFL) theories describe the strongly correlated and coherent low-energy dynamics of quantum dot devices, and extends to out-of-equilibrium regimes, aimed at triggered single electron emission.
Symmetry Properties of Mixed and Heat Photo-Assisted Noise in the Quantum Hall Regime
Focusing on the cases of a cosine and Lorentzian periodic drive, it is shown that the different symmetries of the photo-assisted tunneling amplitudes strongly affect the overall profile of these quantities as a function of the AC and DC voltage contributions.
Periodic Energy Transport and Entropy Production in Quantum Electronics
From a thermodynamical perspective recent investigations on nonstationary heat and work generated in quantum systems, emphasizing open questions and unsolved issues are discussed.
Single-particle emission at finite temperatures
The state of particles injected onto the surface of the Fermi sea depends essentially on the temperature. The pure state injected at zero temperature becomes a mixed state if injected at finite
