Thermodynamics of adiabatic quantum pumping in quantum dots
Daniele Nello, Alessandro Silva
We consider adiabatic quantum pumping through a resonant level model, a single-level quantum dot connected to two fermionic leads. Using the tools of adiabatic expansion, we develo…
Phase coherence, inelastic scattering, and interaction corrections in pumping through quantum dots
Davide Fioretto, Alessandro Silva
Adiabatic quantum pumping in noninteracting, phase coherent quantum dots is elegantly described by Brouwer's formula. Interactions within the dot, while suppressing phase coherence…
Adiabatic pumping through a quantum dot in the Kondo regime: Exact results at the Toulouse limit
Avraham Schiller, Alessandro Silva
Transport properties of ultrasmall quantum dots with a single unpaired electron are commonly modeled by the nonequilibrium Kondo model, describing the exchange interaction of a spi…
Multiphoton Processes in Driven Mesoscopic Systems
Alessandro Silva, Vladimir E. Kravtsov
We study the statistics of multi-photon absorption/emission processes in a mesoscopic ring threaded by an harmonic time-dependent flux . For this sake, we demonstrate a usefu…
Tail States below the Thouless Gap in SNS junctions: Classical Fluctuations
Alessandro Silva
We study the tails of the density of states (DOS) in a diffusive superconductor-normal metal-superconductor (SNS) junction below the Thouless gap. We show that long-wave fluctuatio…
Comment on "Do Intradot Electron-Electron Interactions Induce Dephasing?"
Jürgen König, Yuval Gefen, Alessandro Silva
In a recent Letter, Jiang, Sun, Xie and Wang [Phys. Rev. Lett. 93, 076802 (2004), cond-mat/0408261] study transport through an interacting quantum dot embedded in one arm of an Aha…
