Transition to this phenomenon is marked by a discontinuous jump in electric heat capacity. One theory about this phenomenon introduced the concepts of coherence length and penetration depth, explaining small perturbations in density and the decay of external magnetic fields. That theory is named for Ginzburg and Landau. Explained by the condensation of electrons into phonon-exchanging Cooper Pairs, materials exhibiting this phenomenon expel magnetic fields in an effect named for Meissner. For 10 points, name this phenomenon which occurs at very low temperatures and is defined as the absence of electrical resistance.
