Query: Dynamically current-driven de Gennes -St James states in
  Metal-Superconductor junctions   We investigate the conductance of a Normal-Normal'-Superconductor (NN'S)
junction, in which current injection destroys superconductivity in a small
region N' of the superconductor, with a size varying with the applied voltage
V. Voltage-dependent de Gennes-Saint James (dGSJ) bound states appearing in the
N' slab lead to two distinct sets of conductance oscillations. We show that
this effect significantly alters the conductance of systems for which
$\kappa^2v_F \sim 10^9$ m/s such as pnictides ($\kappa$ and $v_F$ being the
Ginzburg number and the Fermi velocity, respectively), and we discuss their
consequences on the identification of the bosonic modes of strongly coupled
superconductors.
