Renormalization of the Coulomb Law in an Amorphous System of Metallic Nanospheres and Its Impact on the Electronic Subsystem

Abstract

We demonstrate relations between the renormalization of the Coulomb interaction in a disordered system of metallic nanospheres and the changes induced by this renormalization in the spectrum of the electronic subsystem of nanospheres. Emergence of bound electron pairs with a total spin equal to zero inside these nanopspheres is predicted on the basis of the proposed model. This phenomenon can be a reason of high-temperature superconductivity in such a system.
