Superconductors, as physical systems, are materials that, below a critical temperature, exhibit exactly zero DC electrical resistance and expel interior magnetic fields via the Meissner effect, indicating a thermodynamic phase distinct from ordinary conductors. Their behavior is described microscopically by Bardeen–Cooper–Schrieffer (BCS) theory for conventional superconductors, where electrons form Cooper pairs that condense into a macroscopic quantum state with a complex order parameter and an energy gap in the excitation spectrum. Superconductors also display quantization of magnetic flux, support dissipationless supercurrents, and exhibit rich phase diagrams influenced by temperature, magnetic field, and material structure.
