A model of it can be extended into the 4-dimensional Coleman-Weinberg model, and a value of one over the square root of two for the model's namesake parameter separates two classes of it.
A model of it can be extended into the 4-dimensional Coleman-Weinberg model, and a value of one over the square root of two for the model's namesake parameter separates two classes of it. The discovery of the isotope effect in mercury provided experimental evidence for another theory of this phenomenon and the ratio of the coherence length to penetration depth is the basis of the Ginzburg-Landau theory. Phonon exchange with the crystal lattice condenses two electrons into a Cooper pair in the model that explains the Meissner effect, known as the BCS theory. For 10 points, name this phenomenon in which a material has no electrical resistance.
