摘要
We discuss the destruction of superconductivity in quasi-one-dimensional systems due to the interplay between disorder and Coulomb repulsion. We argue that to understand the behavior of the system one has to study both fermionic and bosonic mechanisms of suppression of superconductivity. The former describes reduction in the mean field critical temperature , while the latter refers to thermal and quantum fluctuations in the order parameter. A change in parameters such as wire width and disorder strength significantly affects both mechanisms.
