No liquid helium, but still extremely cool

NIST scientists have devised a novel hybrid system for cooling superconducting nanowire single-photon detectors (SNSPD) – essential tools for many kinds of cutting-edge research – that is far smaller than those previously ...

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 ...

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 ...

Portable superconductivity systems for small motors

Superconductivity, where electrical currents course unhindered through a material, is one of modern physics' most intriguing scientific discoveries. It has many practical uses. Governments, industries, and health care and ...

Physicists manipulate Abrikosov vortices

A nanophotonics group led by Prof. Brahim Lounis of the University of Bordeaux, including scientists from MIPT, has performed a unique experiment involving the optical manipulation of individual Abrikosov vortices in a superconductor. ...

New clues emerge in 30-year-old superconductor mystery

One of the greatest mysteries of experimental physics is how so-called high-temperature superconducting materials work. Despite their name, high-temperature superconductors—materials that carry electrical current with no ...

Physicists pass spin information through a superconductor

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have made a discovery that could lay the foundation for quantum superconducting devices. Their breakthrough solves one the main ...
