Query: Theoretical explanation of electric field-induced superconductive
  critical temperature shifts in Indium thin films   We calculate the effect of a static electric field on the superconductive
critical temperature of Indium thin films in the framework of proximity effect
Eliashberg theory, in order to explain 60 years old experimental data. Since in
the theoretical model we employ all quantities of interest can be computed
ab-initio (i.e. electronic densities of states, Fermi energy shifts and
Eliashberg spectral functions), the only free parameter is in general the
thickness of the surface layer where the electric field acts. However, in the
weak electrostatic field limit Thomas-Fermi approximation is still valid and
therefore no free parameters are left, as this perturbed layer is known to have
a thickness of the order of the Thomas-Fermi screening length. We show that the
theoretical model can reproduce experimental data, even when the magnitude of
the induced charge densities are so small to be usually neglected.
