The Oscilloscope and the Function Generator
courses.washington.eduprovide a speci ablevoltage applied over a speci abletime, suchas a \sine wave" or\triangle wave" signal. These signals are used to control other apparatus to, for example, vary a magnetic eld (superconductivity and NMR experiments) send a radioactive source back and forth (M ossbauer e ect experiment), or act as a timing signal, i.e., \clock ...
The London Equations - University of California, San Diego
courses.physics.ucsd.edusuperconductivity is somehow invisible to the superconducting charges themselves. Further, to suggest that the charges flow without friction implies, as the Londons put it, “a premature ... like to point out that in the wake of BCS theory an equivalent analysis can be applied to the nonlocality induced by the formation of Cooper pairs. Though ...
Chapter 10: Superconductivity
www.phys.lsu.eduFigure 5: Superconductivity is destroyed by either raising the temperature or by ap-plying a magnetic eld. 2 The London Equations London and London derived a phenomenological theory of su-perconductivity which correctly describes the Meissner e ect. They assumed that the electrons move in a frictionless state, so that mv_ = eE (7) or, since @j ...

Moreover, the sputtering machine that Schön used to apply the Al2O3 films was located, not at Bell Labs, but in his former PhD lab at the University of Konstanz in Germany.
