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.
A puzzling form of superconductivity that arises only under strong magnetic fields has been mapped and explained by a research team including Andriy Nevidomskyy, professor of physics and astronomy at Rice University. Their ...

Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable electrical conduction. When they are bound, or "heavy," they can act as insulators. However, in certain ...
