Nonlinear electrodynamics near a superconducting string
Abstract
We calculate the effective action for photons in an arbitrary external field using the expansion in the inverse of the mass of the electron. The resulting effective lagrangian is used to calculate magnetization of the vacuum in the vicinity of a superconducting string. The magnetization current partially screens the current in the string and slows down the rate of growth of the current there. We also discuss the scattering of electromagnetic waves on a superconducting string with the nonlinear effects taken into account.
