Team activity

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.

Research Topics
Superconductivity in inhomogeneous materials. Vortex, Superconductor-Insulator transition, proximity effect.
Design of STM microscopes. Learn more at my group web site.
