3. Evaluation AERES Electronic transport in mesoscopic and nanoscopic devices • Transport through a single molecule; effect of the internal degrees of freedom (spin, phonons, …) • Superconducting and hybrid systems (Josephson effect, Multiple Andreev reflection, etc.)‏ • 1d conductors with electronic interactions – Luttinger liquid (Carbon nanotubes, edge states of the Quantum Hall effect, …)‏ • High frequency noise, theory of noise measurement • Time-dependent problems – time-resolved single electron excitations • Theory of Quantum Hall effect (impact of the atomic lattice, anomalous and spin Hall effects, …)‏

9. Evaluation AERES Projets en cours – possibilités de séminaires, stages, thèses… Emission et manipulation d’électrons uniques dans des états de bords : Optique quantique électronique (ANR 1 shot, coll. LPA ENS Paris, ENS Lyon)‏ Effets thermo-électriques dépendant du temps (coll. F. Michelini, IM2NP) Etude du splitter à paire de Cooper”,et du courant de quartets (paires de paires de Cooper) (coll. R. Melin Grenoble, T. Kontos Paris)‏

10. Evaluation AERES Josephson effect through an isotropic magnetic molecule Phase diagram of the Josephson junction (0 or p state). The exchange interaction J has a deep impact on the Joseph-son current M. Lee, T. Jonckheere and T. Martin, Phys. Rev. Lett. 101, 146804 (2008)‏

11. Evaluation AERES Screening in a Luttinger liquid coupled to a STM tip Study of the impact of screening on the transport between a STM tip and a Luttinger liquid Calculation of the spectral properties and of transport properties (screening reduces the current).

12. Evaluation AERES Dynamic response of the quantum RC circuit with strong electronic interactions Systematic study of the effect of strong electronic interaction on the dynamical behavior of the quantum RC circuit, using a Luttinger liquid model. Relaxation resistance is universal even for strong Coulomb blockade, but strong interactions in the leads induce a quantum phase transition to an incoherent regime Y. Hamamoto, T. Jonckheere, T. Kato and T. Martin, Phys. Rev. B 81, 153305 (2010) (from LPA Physique mésoscopique group)
