However these theories do not explain the Meissner effect: the process by which a magnetic field is expelled from the interior of a metal undergoing a transition to the superconducting state. Nor do they provide a dynamical explanation of the London moment generation.
The following papers explain why BCS-London theory can't explain the
Meissner effect
and offer an explanation for it:
superconductors expel magnetic field because they expel
negative charge
