Electrodynamics of superconductors
... assuming that no longitudinal electric fields (i.e. ∇ 0) can exist inside superconductors, as can be seen by applying the divergence operator to Eq. (1a). However, the possibility of an electrostatic field inside superconductors was recently suggested by the theory of hole superconductivity[5, 6, 7] ...
