SIT Conference

In 2014 we organize a conference on strongly disordered superconductors in Villard de Lans. strongly disordered superconductors are attracting much interest due to the intriguing new states of matter that exist in the vicinity of the superconductor-insulator transition (SIT) and due to their potential applications in THz detection of astronomical signals and in quantum information devices.

More info on the conference website.
