Pippard theory

WebbThe theory yields a second-order phase transition and a Meissner effect in the form suggested by Pippard. Calculated values of specific heats and penetration depths and their temperature variation are in good agreement with experiment. There is an energy gap for individual-particle excitations which decreases from about 3. 5 k T c at T = 0 ° K ... WebbDeviations from the London theory occur for a thickness less than twice the penetration depth and give a susceptibility smaller than the London value. Largest deviation is found for the Pippard theory and least for the Schafroth-Blatt version. The experimental data of Lock are inconclusive with regard to the validity of the nonlocal theories.
