A phenomenological theory of these was developed by Lev Landau and Vitaly Ginzberg.
When these materials interface with other materials, Andreev (ahn DREE yev) reflection can occur. A phenomenological theory of these was developed by Lev Landau and Vitaly Ginzberg. They expel magnetic fields from their interior in the Meissner Effect. Coming in Type I and Type II varieties, these materials are described as the result of electrons condensing into Cooper pairs by BCS theory. For 10 points, name these materials, which have zero resistance at low temperatures.
