Query: Proximity Effect in Presence of Quantum Fluctuations   The effect of Coulomb interaction upon superconductive proximity effect in
disordered metals is studied, employing newly developed Keldysh functional
approach (cond-mat/9907358).
  We have calculated subgap Andreev conductance between superconductor and 2D
dirty film, as well as Josephson coupling via such a film. Both two
qualitatively different Coulomb effects - suppression of the tunneling density
of states and disorder-enchanced repulsion in the Cooper channel - are shown to
be important at sufficiently low temperatures.
