| Abstract: |
This article focuses on a simplified "toy model" based on electrostatic interactions to help undergraduate students conceptually understand Cooper pair formation in superconductivity, as explained by the Bardeen–Cooper–Schrieffer (BCS) theory. The model demonstrates how lattice distortions and atomic number influence the emergence of an effective attractive force between two electrons, despite their natural repulsion, by considering static Coulomb forces within one- and two-dimensional lattice configurations. While the model successfully illustrates the role of lattice ions and vibrations in pairing, it operates within classical electrostatics, omitting quantum mechanical aspects such as electron spin, electron momentum, and magnetic properties, and thus cannot predict critical superconducting parameters like coherence length accurately or the critical temperature. The study provides a pedagogical tool for classroom discussion rather than a comprehensive physical theory, with supplementary computational resources available for further exploration.
