Описание: In this book author present a review of theoretical and experimental works on the problem of mutual interplay of Anderson localization and superconductivity in strongly disordered systems. Superconductivity exists close to the metal-insulator transition in some disordered systems such as amorphous metals, superconducting compounds disordered by fast neutron irradiation etc. High-temperature superconductors are especially interesting from this point of view. Mainly bulk systems are considered, superconductor-insulator transition in purely two-dimensional disordered systems is not discussed in any detail, though nowadays it is a very active field of both experimental and theoretical research.
