Chiral symmetry breaking and the Josephson current in a ballistic superconductor–quantum wire–superconductor junction
We evaluate the Josephson current through a quasi-1D quantum wire coupled to bulk superconductors.
 It is shown that the interplay of Rashba spin–orbit interaction and Zeeman splitting results

| description | We evaluate the Josephson current through a quasi-1D quantum wire coupled to bulk superconductors.
It is shown that the interplay of Rashba spin–orbit interaction and Zeeman splitting results
in the appearence of a Josephson current even in the absence of any phase difference between
the superconductors. In a transparent junction (D≅1) at low temperatures this anomalous
supercurrent Jan appears abruptly for a Zeeman splitting of the order of the Andreev level spacing
as the magnetic field is varied. In a low transparency (D << 1) junction one has Jan √D under
special (resonance) conditions. In the absence of Zeeman splitting the anomalous supercurrent disappears.
We have investigated the influence of dispersion asymmetry induced by the Rashba interaction
in quasi-1D quantum wires on the critical Josephson current and have shown that the breakdown
of chiral symmetry enhances the supercurrent.
