“…We compare our formulas with the numerical results of a Floquet calculation properly modeling the emission process from a realistic periodic source . This emitter consists of the mesoscopic capacitor : a quantum dot with discrete levels connected through a QPC to the edge state that is driven by a gate applying a periodic square drive

The analog of two seminal quantum optics experiments are considered in a condensed matter setting with single electron sources injecting electronic wave packets on edge states coupled through a quantum point contact. When only one electron is injected, the measurement of noise correlations at the output of the quantum point contact corresponds to the Hanbury-Brown and Twiss setup. When two electrons are injected on opposite edges, the equivalent of the Hong-Ou-Mandel collision is achieved, exhibiting a dip as in the coincidence measurements of quantum optics. The Landauer-Buttiker scattering theory is used to first review these phenomena in the integer quantum Hall effect, next, to focus on two more exotic systems: edge states of two dimensional topological insulators, where new physics emerges from time reversal symmetry and three electron collisions can be achieved; and edges states of a hybrid Hall/superconducting device, which allow to perform electron quantum optics experiments with Bogoliubov quasiparticles.Comment: 13 pages, 10 figures, invited contribution for a focus issue on "Single-electron control in solid-state devices

“…These recent efforts have boosted the general interest in the study of noise [30] as a powerful tool to characterize the response of a conductor to a generic time-dependent driving potential [17,28,29,[31][32][33][34][35][36]. In particular, it has been shown that the noise carries information on the probability with which electron-hole pairs are created by the ac part of the driving [31,37,38] and it is sensitive to correlations between electrons and holes [39].…”

Energy and power fluctuations in ac-driven coherent conductors

Using a scattering matrix approach we study transport in coherent conductors driven by a time-periodic bias voltage. We investigate the role of electron-like and hole-like excitations created by the driving in the energy current noise and we reconcile previous studies on charge current noise in these kinds of systems. The energy noise reveals additional features due to electron-hole correlations. These features should be observable in power fluctuations. In particular, we show results for the case of a harmonic and biharmonic driving and of Lorentzian pulses applied to a two-terminal conductor, addressing recent experiments [Gabelli and Reulet, Phys. Rev. B 87, 075403 (2013) and Dubois et al., Nature (London) 502, 659 (2013)].

Dephasing in single-electron generation due to environmental noise probed by Hong-Ou-Mandel interferometry

et al. 2014

We consider the effect of dephasing on a quantum dot which injects single electrons on a chiral edge channel of the quantum Hall effect. Dephasing is described by the coupling of the dot to a bosonic bath which represents the electromagnetic environment. Using the input-output formalism of quantum optics, we derive the density matrix of the edge degrees of freedom. Results are illustrated by computing the zero frequency current-current correlations when two such single-electron emitters achieve a collision at the location of a quantum point contact, in the same spirit as the Hong-Ou-Mandel experiment of quantum optics. Such correlations are directly linked to the quantum mechanical purity. We show that, as observed in a recent experiment, the effect of dephasing leads to a lifting of the Hong-Ou-Mandel dip when the time delay between the two electron wave packets is zero. Generalizations to time filtered wave packets as well as to asymmetric, detuned injection between opposite edges are obtained.
