“…This current is twice bigger than the magnitude of the Josephson current calculated for a single-mode junction within the tunnel model [2] and beyond it [16]. However, in order to get the total current one has to take into account the contribution from the continuum:…”

We study the microscopic structure of the Josephson current in a single-mode tunnel junction with a wide quasiclassical tunnel barrier. In such a junction each Andreev bound state carries a current of magnitude proportional to the amplitude of the normal electron transmission through the junction. Tremendous enhancement of the bound state current is caused by the resonance coupling of superconducting bound states at both superconductor-insulator interfaces of the junction. The possibility of experimental observation of the single bound state current is discussed.Typeset using REVT E X 1
