Superconductivity
Superconductivity is the phenomenon in which certain materials conduct electricity with exactly zero resistance below a characteristic critical temperature, accompanied by the complete expulsion of magnetic fields known as the Meissner effect.
Overview
Discovered by Heike Kamerlingh Onnes in 1911, superconductivity defied classical physics until BCS theory (Bardeen, Cooper, and Schrieffer, 1957) explained it through correlated electron pairs — Cooper pairs — mediated by lattice vibrations, a genuinely quantum mechanical effect. High-temperature superconductors discovered in the 1980s still lack a complete theoretical explanation, making the phenomenon an active frontier of condensed matter physics.
Why it matters
Superconducting materials have profoundly shaped medical technology: MRI scanners depend on powerful superconducting magnets to generate the strong, stable fields required for imaging. In quantum computing, superconducting circuits are the foundation of the most advanced qubit hardware. Room-temperature superconductivity would revolutionize power transmission and remain one of the most critical unsolved challenges in materials science with major implications for energy infrastructure.
