These entities' free energy is minimized when "del squared of B equals B over lambda squared," according to the London equation.
These entities' free energy is minimized when "del squared of B equals B over lambda squared," according to the London equation. They are characterized by the coherence length and penetration depth in Ginzburg-Landau theory, and they are classified as Type I or Type II. These substances' properties arise from phonon exchanges between Cooper pairs of electrons, and they become perfectly diamagnetic by expelling magnetic fields from their interior. Governed by BCS theory and exhibiting the Meissner effect, they typically exist at low temperatures. For 10 points, name these materials with zero electrical resistance.
