London- vs Josephson penetration depth

  1. Apr 12, 2010 #1
    Hi everyone. What is the difference between the London penetration depth and the Josephson penetration depth? Both of them have to do with the penetration of a magnetic field into the superconductor as far as I can see...

    The London penetration depth has to do with the distance flux penetrates into a bulk superconductor.
    The Josephson penetration depth has to do with the flux distribution of in a long Josephson junction. The latter does not explicitly depend on the properties of the superconductors that form the juncion (although there is an implicit dependence due to jc)
