Abstract

The suppression of the mean field temperature of the superconducting transition, Tc, in homogeneous amorphous wires is studied. We develop a theory that gives Tc in situations when the dynamically enhanced Coulomb repulsion competes with the contact attraction. The theory accurately describes recent experiments on Tc suppression in superconducting wires, after a procedure that minimizes the role of nonuniversal mechanisms influencing Tc is applied.
