Organic superconductors and quantum criticality in molecular matter

Claude Bourbonnais

Université de Sherbrooke

In this talk, I shall discuss the origin of organic superconductivity in extremely anisotropic or nearly one-dimensional molecular metals. A wide variety of experiments indicates that superconductivity is unconventional in these systems, emerging from quantum fluctuations associated to the critical suppression of antiferromagnetic ordering temperature under applied pressure. I will highlight some recent success made by scaling theory in the elaboration of a microscopic description of quantum criticality in these compounds, together with its impact in the development of an anomalous metallic phase and the mechanism of superconductivity.
