Query: Magnetic field influence on the proximity effect in semiconductor -
  superconductor hybrid structures and their thermal conductance   We show that a magnetic field can influnce the proximity effect in NS
junctions via diamagnetic screening current flowing in the superconductor.
Using ballistic quasi-one-dimensional (Q1D) electron channels as an example, we
show that the supercurrent flow shifts the proximity-induced minigap in the
excitation spectrum of a Q1D system from the Fermi level to higher
quasiparticle energies. Thermal conductance of a Q1D channel (normalized by
that of a normal Q1D ballistic system) is predicted to manifest such a spectral
feature as a nonmonotonic behavior at temperatures corresponding to the energy
of excitation into the gapful part of the spectrum.
