Superconductor-Insulator transition driven by disorder

I will begin by reviewing the experimental data on the superconductor-insulator transition in InO, TiN and similar films. I will argue that the transition in these materials is driven entirely by the competition of the disorder and attraction. I will discuss the solution of the simplest mathematical model that has these ingredients and show that the resulting quantum critical point has many anomalous and unexpected features. I will present the recent data that confirm some of the predictions of the theory.
