Cracking the mystery of perfect superconductor efficiency
The next big leap came in 1957, when John Bardeen, Leon Cooper, and John Robert Schrieffer proposed the first theory of why superconductivity occurs. Their theory, made possible by the support of DOE's predecessor, the Atomic Energy Commission, also ...
Titan shines light on high-temperature superconductor pathway
In conventional, low-temperature superconductivity (left), so-called Cooper pairing arises from the presence of an electron Fermi sea. In the pseudogap regime of the cuprate superconductors (right), parts of the Fermi sea are "dried out" …more.
Superconductivity Hypothesis Gets Some Experimental Confirmation
Transition temperatures tend to be close to 0 K or -273 C. At even slightly higher temperatures, the materials tend to lose their superconducting properties; indeed, at room temperature most superconductors are very poor conductors. Superconductors are ...
A proposed superconductivity theory receives exclusive experimental confirmation
In 1987, some high-temperature superconductors, called cuprates, were discovered by physicists Georg Bednorz and Alexander Müller, so named because they all contain copper and oxygen. These new materials have properties which have raised profound ...
