Dynamic theory for disordered superconductivity

The dynamic theory for disordered superconductivity was suggested based on the fracton-electron interaction. It was demonstrated that electrons in disordered superconductors can feel an attractive interaction by the exchange of virtual fractons. A normal state is unstable with respect to such an interaction, and a superconducting state is formed through the association of electrons in pairs with opposite wave vectors and spins. The critical temperature for percolation superconducting model can be derived from this theory.
