| dc.description | The RCSJ model of resistively and capacitively shunted Josephson junctions is used to describe superconducting point contacts over a wide range of resistances up to the metallic -- tunneling transition. Their small dynamic capacitance of order $C = 0.1 $fF due to the point-contact geometry results in a huge plasma frequency. The critical current is then strongly suppressed and the contact resistance becomes finite because of quantum-mechanical zero-point fluctuations of the Josephson plasma and the rather large escape rate out of the zero-voltage state due to quantum tunneling. We test the predictions of the RCSJ model on the classical superconductors lead, indium, aluminum, and cadmium. | |
| dc.description | 28 pages, 24 figures, We apologize for the large size due the horrible postscript drivers of all M$-Windows graphics programs, we used. Changes: reducing the size of the figures by streamlining the postscript files. Thanks to Thorsten Schwander of xxx server!. accepted for publication in J. Low Temp. Phys. vol 116 | |
