Description

Ce cours vise à introduire la supraconductivité à travers des expériences historiques ou récentes et les concepts théoriques nécessaires.

L’examen consistera en une présentation de 20 ou 30 minutes d’un article de recherche.

Plan du cours

A – Introduction à la supraconductivité

Introduction, phénoménologie, thermodynamique, effet Meissner
Effet isotopique et hamiltonien BCS
Le problème de Cooper, L’ansatz BCS
Théorie BCS à T=0 et T>0
Approche de champ moyen, transformation de Bogoliubov
Equations de Bogoliubov de Gennes et effets de proximité

B – Supraconductivité mésoscopique

Jonction Normal-Isolant-Supraconducteur (NIS), quasi-particules et courants d’Andreev
Jonctions hybrides normal-supraconducteur (NS). Régimes ballistiques et diffusifs
Jonctions supraconductrices et états liés d’Andreev : Jonctions SIS et SNS
Grains supraconducteurs et petites jonctions. Effet de charge.
