Low-temperature States of matter
Superconductor Superconductors are materials that have zero electrical resistivity, and therefore perfect conductivity. This is a distinct physical state which exists at low temperature, and the resistivity increases discontinuously to a finite value at a sharply-defined transition temperature for each superconductor. A superconductor also excludes all magnetic fields from its interior, a phenomenon known as […]
