They can be condensed into one equation in a namesake gauge where the Laplacian of Coulomb potential is zero. Applying Ampere's law to one of them and taking the curl of both sides gives an equation that relates the Laplacian of the B-field to a characteristic quantity; that quantity, which scales as the one half power of the (*) supercurrent density, is the distance at which the B field decays to B naught over e.

Applying Ampere's law to one of them and taking the curl of both sides gives an equation that relates the Laplacian of the B-field to a characteristic quantity; that quantity, which scales as the one half power of the (*) supercurrent density, is the distance at which the B field decays to B naught over e. One of them relates the time derivate of the superconducting current to the electric field and the other relates the curl of the current to the magnetic field. The aforementioned characteristic constant is the "penetration depth" given by these equations, which are able to describe the Meissner effect. For 10 points, identify these equations named for two brothers, one of who also lends his name to some dispersion forces.
