Abstract : Following on from last week talk, we will delve into a main example of topological tools: the theory of unconventional superconductors. Superconductivity was first observed a century ago. However, the BCS theory, the first satisfying understanding of this phenomenon, was formalized in 1957. This satisfaction lasted a couple of decades, until experimentalists discovered a variety of exotic superconductors, poorly described by BCS. Over the last 20 years, the use of topology provided a more relevant background to describe these materials. In this talk, we will briefly recall the phenomenology of superconductors. Then we will explain the BCS theory. Finally, we will get to a theory beyond BCS, the so-called chiralsuperconductors.
Le séminaire des doctorant⋅es de l’I2M et du CPT à Luminy regroupe chaque semaine les doctorant⋅es du site autour d’un exposé plus ou moins (in)formel, dans un cadre convivial. Il est évidemment ouvert aux étudiant⋅es de master et aux doctorant⋅es d’autres laboratoires.
Pour le moment, le séminaire a lieu dans la salle 500-504b du TPR2, au 5ème étage.
