Immanuel Bloch's group recently observed bosonic ladders that undergo a low-dimensional version of this effect. A dual of this effect is used to explain quark confinement in the MIT bag model. A pair of equations governing this effect can be combined into one by using the Coulomb gauge, which then sets J equal to negative n sub e squared over m c times the vector potential; combining that equation with Ampere's Law gives a characteristic (*) length scale for this effect. This effect occurs due to vortices of supercurrent that swirl around the surface, which allows the substance undergoing this effect to have a magnetic susceptibility equal to negative one. The explanation of this effect is one of the successes of BCS theory. For 10 points, name this effect in which external magnetic fields are expelled from the inside of a superconductor.
