Query: Noncentrosymmetric superconductors in one dimension   We study the fermionic boundary modes (Andreev bound states) in a
time-reversal invariant one-dimensional superconductor. In the presence of a
substrate, spatial inversion symmetry is broken and the electronic properties
are strongly affected by an antisymmetric spin-orbit coupling. We assume an
arbitrary even number of nondegenerate bands crossing the Fermi level. We show
that there is only one possible pairing symmetry in one dimension, an analog of
s-wave pairing. The zero-energy Andreev bound states are present if the sign of
the gap function in an odd number of bands is different from all other bands.
