Query: Resonant Andreev Scattering In Phase-Coherent, Superconducting
  Nanostructures   Analytic predictions for resonant transport in three generic structures are
presented. For a structure comprising a normal (N) contact - normal dot (NDOT)
- superconducting (S) contact, we predict that finite voltage, differential
conductance resonances are destroyed by the switching on of superconductivity
in the S-contact. In the weak coupling limit, the surviving resonances have a
double-peaked line-shape. Secondly, we demonstrate that resonant Andreev
interferometers can provide galvonometric magnetic flux detectors, with a
sensitivity in excess of the flux quantum. Finally, for a superconducting dot
(SDOT) connected to normal contacts (N), we show that the onset of
superconductivity can increase the sub-gap conductance, in contrast with the
usual behaviour of a tunnel junction.
