0 a substance, especially a metal, that allows an electrical current to move freely through it at a very low temperature
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.
