Charge expulsion and Spin Meissner effect in superconductors

I argue that the Meissner effect (expulsion of magnetic field from the interior of a metal going into the superconducting state) cannot be explained by the conventional BCS-London theory, hence that BCS-London theory is incorrect[1]. The theory of hole superconductivity explains the Meissner effect as arising from the expulsion of negative charge from the interior of the superconductor towards the surface, resulting in a non-homogeneous charge distribution, a macroscopic electric field in the interior, and a spin current near the surface (Spin Meissner effect). Electrodynamic equations describing this scenario will be discussed[2]. In the charge sector, these equations are related to electrodynamic equations originally proposed by the London brothers[3] but shortly thereafter discarded by them[4]. [1] J.E.
