John Robert Schrieffer

John Robert Schrieffer was an American physicist renowned for his significant contributions to the understanding of superconductivity. In 1957, he co-developed the BCS theory, named after him and his colleagues John Bardeen and Leon Cooper. This theory explains how certain materials can conduct electricity without resistance at very low temperatures. Essentially, it describes how pairs of electrons, called Cooper pairs, interact with the lattice structure of a material, leading to this unusual and fascinating phenomenon. Schrieffer's work has had profound implications in physics, materials science, and technology, influencing areas such as quantum computing and magnetic resonance imaging.
