We consider a Hong-Ou-Mandel interferometer for Lorentzian voltage pulses applied to quantum Hall edge channels at filling factor ν=2. Due to interedge interactions, the injected electronic wave packets fractionalize before partitioning at a quantum point contact. Remarkably enough, differently from what was theoretically predicted and experimentally observed by using other injection techniques, we demonstrate that when the injection occurs through time-dependent voltage pulses (arbitrarily… Expand

Auto- versus Cross-Correlation Noise in Periodically Driven Quantum Coherent Conductors
Analysis of shot noise in terms of these contributions allows us to predict that no individual traveling particles with a real wave function, such as Majorana fermions, can be created in the Fermi sea in a clean manner, that is, without accompanying electron–hole pairs. Expand

A linear energy loss rate is indicated as the best candidate for describing the behavior of the quasi-particle peak at short enough propagation lengths. Expand

Dephasing in the electronic Mach-Zehnder interferometer at filling factor ν=2
We propose a simple physical model which describes dephasing in the electronic Mach-Zehnder interferometer at filling factor ν=2. This model explains very recent experimental results, such as theExpand

Interactions and charge fractionalization in an electronic Hong-Ou-Mandel interferometer.
This work considers an electronic analog of the Hong-Ou-Mandel interferometer, where two single electrons travel along opposite chiral edge states and collide at a quantum point contact and shows that charge and neutral modes interfere with each other, leading to satellite dips or peaks in the current noise.

Resonant dephasing in the electronic Mach-Zehnder interferometer.
It is argued that the measured lobe structure in the visibility of oscillations and the phase rigidity result from a strong long-range interaction between two adjacent counterpropagating edge states, which leads to a resonant scattering of plasmons. Expand
Crystallization of levitons in the fractional quantum Hall regime
Using a periodic train of Lorentzian voltage pulses, which generates soliton-like electronic excita-tions called Levitons, we investigate the charge density backscattered off a quantum point contactExpand
