Strongly correlated and mesoscopic systems
After an experimental PhD on superconducting quantum bits, performed in Saclay (1999-2002), Audrey became a theorist of hybrid mesoscopic and nanoscopic structures. She was a post-doc in Basel, Orsay and Paris (2002-2008), working on spin dependent transport in quantum dot circuits as well as superconducting and ferromagnetic proximity effects in diffusive hybrid circuits. Audrey is now a permanent CNRS researcher at the Laboratoire Pierre Aigrain, working in close collaboration with the experimental "Hybrid Quantum Circuits" team headed by Takis Kontos. She is presently focusing on the development of Cavity Quantum Electrodynamics with hybrid nanocircuits.
At the mesoscopic scale, Coulomb interactions and quantum interferences play a major role, due to electronic confinement. Our purpose is to understand how these properties arise in different types of systems. We first study two dimensional electron gases, in which a strong magnetic field can cause a fractional quantum Hall effect. We also investigate the electronic transport properties of nanostructures made out of molecules (nanotubes, fullerenes, etc.) or semiconductor quantum dots. At last, we study the behavior of superconducting/ferromagnetic hybrid circuits.
