Topological properties of superconducting junctions

Abstract:
Motivated by recent developments in the field of one-dimensional
topological superconductors, we investigate the topological properties of
$s$-matrix of generic superconducting junctions where dimension should not
play any role. We argue that for a finite junction the $s$-matrix is always
topologically trivial. We resolve an apparent contradiction with the previous
results by taking into account the low-energy resonant poles of $s$-matrix.
Thus no common topological transition occur in a finite junction. We reveal a
transition of a different kind that concerns the configuration of the
resonant poles.
