Abstract:

Superconductivity, observed in many metals when cooled to extremely low temperatures, was discovered in 191. In 1986, materials were discovered that superconduct at much more easily obtainable temperatures. This discovery motivated an unprecedented world-wide flurry of research: Not only are applications promising, but these high-temperature superconductors represent a new solid state of matter that break certain fundamental symmetries.
