Tinkham's theory of superconductivity

Tinkham's theory of superconductivity explains how certain materials conduct electricity without resistance below a critical temperature. It describes how electrons pair up into "Cooper pairs" and move coherently, avoiding scattering that causes resistance. The theory emphasizes the importance of quantum coherence and how magnetic fields and temperature influence the superconducting state, leading to phenomena like perfect diamagnetism (Meissner effect). Essentially, Tinkham's work provides a detailed framework for understanding the behavior of superconductors, helping scientists predict and explain their properties.
