The ratio between the penetration depth and coherence length is used in the Ginzburg-Landau theory of this property, which characterizes materials in which electrons condense to form Cooper pairs.
Electrons tunnel between two objects with this property in the Josephson effect. The ratio between the penetration depth and coherence length is used in the Ginzburg-Landau theory of this property, which characterizes materials in which electrons condense to form Cooper pairs. Objects with this property exhibit perfect diamagnetism when they expel a magnetic field in the Meissner effect. YBCO is a high-temperature material exhibiting this property, which comes in Type I or Type II forms. For 10 points, name this property in which materials have no electric resistance.
