Titre |
Dynamical response of nanoconductors: the example of the quantum RC circuit |
|
Résumé |
The ability to probe and manipulate electrons in real time
constitutes one of the main challenges of transport in quantum dots.
One paradigmatic experiment in the topic of high frequency
is the quantum RC circuit, its behavior being governed by
the interplay between quantum coherence and interaction effects.
This circuit is the quantum analogue of the classical RC circuit:
it comprises a dot capacitively coupled to a nearby gate and connected
to a single reservoir lead.
In this talk, I will discuss the emergence of universal and quantized
expressions for the AC resistance of this circuit, and derive an
effective low energy model for this problem. In the case of the
Anderson model, I will show that a giant peak develops in the AC resistance
as the magnetic field is varied. |
