Voorbeelden van superconductor

• It is assumed that there are no currents outside the superconductor, so that the vector potential outside the film is given by (3).

• Hence, we analytically confirm experimental predictions that surface superconductivity may be suppressed by coating a superconductor with a normal metal.

• We consider a superconductor and a normal material, each filling a half-space, in the presence of a constant magnetic field parallel to their interface.

• One can create pairs of special quasi-particles, called anyons, in a 2-dimensional plane sandwiched between two blocks of a superconductor.

• This model could equally well be applied to a boundary between different superconductors, superconductor-insulator, or superconductor-normal metal.

• Current interest embraces the reconnection of vortex lines in superfluids and superconductor s, as well as the more classical problems involving magnetic field lines in plasmas.

• There has been some talk in the past about a superconductor system using liquid nitrogen to cool the line.

• Since the introduction of new, high-temperature superconductors, efficent transmission with much cheaper and more readily available hydrogen and nitrogen coolants is now feasible.
