Query: Towards a realistic transport modeling in a superconducting nanowire
  with Majorana fermions   Motivated by recent experiments searching for Majorana fermions (MFs) in
hybrid semiconducting-superconducting nanostructures, we consider a realistic
tight-binding model and analyze its transport behavior numerically. In
particular, we take into account the presence of a superconducting contact,
used in real experiments to extract the current, which is usually not included
in theoretical calculations. We show that important features emerge that are
absent in simpler models, such as the shift in energy of the proximity gap
signal, and the enhanced visibility of the topological gap for increased
spin-orbit interaction. We find oscillations of the zero bias peak as a
function of the magnetic field and study them analytically. We argue that many
of the experimentally observed features hint at an actual spin-orbit
interaction larger than the one typically assumed. However, even taking into
account all the known ingredients of the experiments and exploring many
parameter regimes for MFs, we are not able to reach full agreement with the
reported data. Thus, a different physical origin for the observed zero-bias
peak cannot be excluded.
