Query: Rashba spin-orbit coupling and quantum-interference effect for a pair of
  spin-correlated electrons in their tunneling and reflection under a step
  potential   We present both theory and numerical-computation results for the transmission
and reflection probability currents of a charged particle across a potential
step in the presence of a Rashba spin-orbit interaction. By varying kinetic
energy and angle of incident electrons or barrier height, different features
associated with tunneling and reflection of electrons are revealed by
inter-spin-channel electron tunnelings and reflections. These unique properties
are further accompanied by spin-state quantum interference of either a
reflected or transmitted pairs of spin-correlated electrons with the same
kinetic energy but in different spin-orbital states. Such distinctive features
are expected to give rise to a lot of applications in both spintronics and
quantum-computation devices.
