• The critical current of a Josephson junction is an oscillatory function of the enclosed magnetic flux $\mathrm{\ensuremath{\Phi}}$, because of quantum interference modulated with periodicity $h/2e$. We calculate these Fraunhofer oscillations in a two-dimensional (2D) ballistic superconductor\char21{}normal-metal\char21{}superconductor (SNS) junction. For a Fermi circle the amplitude of the oscillations decays as $1/\mathrm{\ensuremath{\Phi}}$ or faster. If the Fermi circle is strongly warped… CONTINUE READING
