Cracking the mystery of perfect superconductor efficiency

In 1911, physicist Heike Kamerlingh Onnes aimed to lower mercury's temperature to as close to absolute zero as possible. He hoped to win a disagreement with Lord Kelvin, who thought metals would stop conducting electricity ...

New quantum criticality discovered in superconductivity

Using solid state nuclear magnetic resonance (ssNMR) techniques, scientists at the U.S. Department of Energy's Ames Laboratory discovered a new quantum criticality in a superconducting material, leading to a greater understanding ...

Weird superconductor leads double life

Until about 50 years ago, all known superconductors were metals. This made sense, because metals have the largest number of loosely bound "carrier" electrons that are free to pair up and flow as electrical current with no ...

Secrets behind high temperature superconductors revealed

(PhysOrg.com) -- Scientists from Queen Mary, University of London and the University of Fribourg (Switzerland) have found evidence that magnetism is involved in the mechanism behind high temperature superconductivity.

Room-temperature superconductor study retracted by Nature

A study published in March claiming the discovery of a superconductor that works at room temperature—a scientific holy grail—has been retracted by the high-profile journal Nature at the request of most of its authors.

Entropy landscape sheds light on quantum mystery

By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new evidence about the possible ...
