52London equations — The London equations, developed by brothers Fritz and Heinz London in 1935, [cite journal last= London first= F. coauthors= H. London month= March title= The Electromagnetic Equations of the Supraconductor journal= Proc. Roy. Soc. (London) volume …
53Superconductor Insulator Transition — The Superconductor Insulator Transition is an example of a quantum phase transition, where upon tuning some parameter in the Hamiltonian, a dramatic change in the behavior of the electrons occurs. The nature of how this transition occurs is… …
54BCS theory — is a microscopic theory of superconductivity, proposed by Bardeen, Cooper, and Schrieffer. It describes superconductivity as a microscopic effect caused by Bose condensation of pairs of electrons.HistoryBCS theory was developed in 1957 by John… …
55Superdiamagnetism — (or perfect diamagnetism) is a phenomenon occurring in certain materials at low temperatures, characterised by the complete absence of magnetic permeability (i.e. a magnetic susceptibility chi {v} = −1) and the exclusion of the interior magnetic… …
56Covalent superconductor — Covalent semiconductors are such solids as diamond, silicon, germanium, silicon carbide and silicon germanium where atoms are linked by covalent bonds. Most of those materials, at least in their bulk form, are well studied and rarely hit the… …
57Pseudogap — A pseudogap is a term from the field of high temperature superconductivity which describes an energy (normally near the Fermi energy) which has very few states associated with it. This is very similar to a gap , which is an energy that has no… …
58Type-II superconductor — A Type II superconductor is a superconductor characterised by its gradual transition from the superconducting to the normal state within an increasing magnetic field. Typically they superconduct at higher temperatures and magnetic fields than… …
59Uranium rhodium germanium — Grenoble High Magnetic Field Laboratory , published in August, 2005 s issue of Science , that uranium rhodium germanium (URhGe) is the first discovered metal that becomes superconducting in the presence of an extremely strong electromagnetic… …
60Cryotron — For the gas filled tube, see Krytron. The cryotron is a switch that operates using superconductivity. The cryotron works on the principle that magnetic fields destroy superconductivity. This simple device consists of two superconducting wires ( e …
