How small can superconductors be?

For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. Understanding superconductivity (or the lack thereof) on the nanoscale is expected to ...

Unparticles may provide a new path to superconductivity

(Phys.org)—Physicists have proposed that a hypothetical form of matter called "unparticles" may play a key role in mediating superconductivity—the ability of certain materials to conduct electricity with zero resistance.

Superconducting refrigerator cools via tunneling cascade

(Phys.org) —Cooling microscopic objects to temperatures near absolute zero requires unconventional refrigeration technologies. One microscale cooling method is superconducting refrigeration, in which refrigerators extract ...
