Abstract: In this talk I will demonstrate that Andreev modes that propagate along
a transparent Josephson junction have a perfect transmission at the point
where three junctions meet. The chirality and the number of quantized
transmission channels is determined by the topology of the Fermi surface
and the vorticity of the superconducting phase differences at the
trijunction. We expect that this Chiral Adiabatic Transmission (CAT) is
observable in nonlocal conductance and thermal transport measurements.
Furthermore, because it does not rely on particle-hole symmetry, CAT is
also possible to observe directly in metamaterials.
