Superconducting secrets solved after 30 years

(Phys.org) —A breakthrough has been made in identifying the origin of superconductivity in high-temperature superconductors, which has puzzled researchers for the past three decades.

New way to measure electron pair interactions

Shoot a beam of light or particles at certain special materials and you will liberate electrons—pairs of them—a phenomenon known as "electron pair emission," which can reveal fundamental properties of the solid and reveal ...

Close look at iron-based superconductor advances theory

(Phys.org)—Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported in the Feb. ...

Dopants dramatically alter electronic structure of superconductor

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously ...

Iron-based superconductors exhibit s-wave symmetry

(Phys.org) -- Condensed-matter physicists the world over are in hot pursuit of a comprehensive understanding of high-temperature superconductivity, not just for its technological benefits but for the clues it holds to strongly ...

Physicist awarded prestigious John Bardeen Prize

James A. Sauls, professor of physics and astronomy in the Weinberg College of Arts and Sciences at Northwestern University, has been awarded the 2012 John Bardeen Prize for his contributions to the theory of unconventional ...
