via lattice distortions. And this is phonon mediated attractions between electrons. Theoretically, the attraction are induced when two electrons exchange a virtue phonon, which can shown rigorously in quantum field theory.

: a theory in physics: electrons can combine into pairs (called Cooper pairs) at low temperatures in order to travel through superconductors without resistance However, electrons normally repel each other, and some intermediary is required to induce them to pair. In the BCS theory the ...

The BCS theory of superconductivity developed in 1957 by Bardeen, Cooper and Schrieffer has been remarkably successful in explaining the properties of superconductors. In addition, concepts from BCS have been incorporated into diverse fields of physics, from nuclear physics and dense quark matter to th...
由于电子是费米子,两个电子就变成了玻色子,从而规避了泡利不相容原理,同时也解释了材料内部大量玻色子的来源。于是,1957 年,巴丁、库珀伙同他们对另一位同事施里弗 (John Robert Schrieffer, 1931-2019)将这些想法整理成了一套完整的常规超导理论,后来被命名为 BCS 理论 (Bardeen-Cooper-Schrieffer theory)。
Starting from the linearized BdG-equation we make the simple observation that pairing can occur between particles with total momenta different from zero, e.g., with equal momentum and opposite spin, in cases of an effective interaction acting in the center-of-mass coordinates.This...
