Explanation of the Meissner Effect and Prediction of a Spin Meissner Effect in Low and High $T_c$ Superconductors

TL;DR

This paper challenges conventional superconductivity theories by proposing charge expulsion as essential for the Meissner effect, predicts a spin Meissner effect, and links high-temperature superconductivity to excess negative charge.

Contribution

It introduces a novel explanation for the Meissner effect based on charge expulsion and predicts a spin Meissner effect in superconductors, offering a new perspective beyond BCS-London theory.

Findings

Superconductors expel charge from their interior during transition.

Predicted existence of a macroscopic electric field and spin current in superconductors.

High temperature superconductivity correlates with systems having excess negative charge.

Abstract

I argue that the conventional BCS-London theory of superconductivity does not explain the most fundamental property of superconductors, the Meissner effect: how is the Meissner current generated, and how is it able to defy Faraday's law? How is its mechanical angular momentum compensated? I propose that superconductivity is impossible unless the metal expels charge from its interior towards the surface in the transition to superconductivity. As a consequence, superconductors in their ground state are predicted to possess a macroscopic electric field in their interior, as well as excess negative charge and a macroscopic spin current near the surface. The system is driven normal when the applied magnetic field is strong enough to bring the spin current to a stop. High temperature superconductivity occurs in systems that have too much negative charge.
