Query: Detecting Perfect Transmission in Josephson Junctions on the Surface of
  Three Dimensional Topological Insulators   We consider Josephson junctions on surfaces of three dimensional topological
insulator nanowires. We find that in the presence of a parallel magnetic field,
short junctions on nanowires show signatures of a perfectly transmitted mode
capable of supporting Majorana fermions. Such signatures appear in the
current-phase relation in the presence or absence of the fermion parity
anomaly, and are most striking when considering the critical current as a
function of flux \Phi, which exhibits a peak at \Phi=h/2e. The peak sharpens in
the presence of disorder at low but finite chemical potentials, and can be
easily disentangled from weak-antilocalization effects. The peak also survives
at small but finite temperatures, and represents a realistic and robust
hallmark for perfect transmission and the emergence of Majorana physics inside
the wire.
