Query: Spin-dependent Andreev reflection in spin-orbit coupled systems by
  breaking time-reversal symmetry   We study theoretically the differential conductance at a junction between a
time reversal symmetry broken spin orbit coupled system with a tunable band gap
and a superconductor. We look for spin-dependent Andreev reflection (i.e,
sub-gap transport) and show that when various mass terms compete in energy,
there is substantial difference of Andreev reflection probability depending on
the spin of the incident electron. We further analyze the origin of such
spin-dependence and show how the incident angle of the electrons controls the
spin-dependence of the transport.
