Abstract
We show that the implementation of the \(1/ c^2 \) transverse current–current interaction between electrons resulting from the non-relativistic QED into the standard self-consistent electron BCS model in bulk under thermal equilibrium in the stable superconductive phase ensures the full compensation of a constant external magnetic field by the internal magnetic field created by the electrons, i.e. one has an ideal diamagnet.

摘要
我们证明,在稳定超导相的热平衡下,将非相对论性QED产生的电子之间的\(1 / c ^ 2 \)横向电流-电流相互作用实现为标准的自洽电子BCS模型由电子产生的内部磁场对恒定的外部磁场进行完全补偿,即具有理想的反磁铁。
