Time-dependent quantum transport in correlated systems: applications to electron quantum optics

Abstract:
In this talk I will describe, from a theoretical point of view, quantum transport in systems smaller than the quantum coherence length, in particular in quantum point contacts (QPC) connected to leads.
Of particular interest are the new phenomena that appear in correlated or interacting mesoscopic systems, such as BCS superconductors or samples in the fractional quantum Hall regime.
Junctions involving such systems are studied when a periodic time-dependent voltage drive is applied.
The case of Lorentzian voltage pulses constitutes one of the tools used in electron quantum optics to generate single electron excitations.
I will give a few illustrations of how can the above-mentioned embedded correlations affect these single electron excitations and how can the latter be used to propose new scenarios of electron quantum optics.
