Superconductivity Observed at Fastest Speed Yet

High speed cameras were first used over one hundred years ago to determine if the hooves of a galloping horse are ever off the ground at the same time. Ever since then, high speed photography has been used to observe a variety of events, and now researchers at the University of British Columbia have developed a new technique to capture the behavior of electrons in superconductors.

Superconductors are materials capable of transmitting electrical currents without resistance, and have been, understandably, of great interest since their discovery. Unfortunately the low temperatures required have limited their use, but by better understanding how the phenomenon occurs, researchers hope to devise room temperatures superconductors. To that end, the UBC researchers combined technologies and techniques to capture the behavior of electrons over just 10 femtoseconds (0.00000000000001 seconds).

The results support the hypothesis that the interactions between one electron and the spin and magnetic pull of the others around it actually delay and mediate electrons interacting with each other.
