Superconductivity does the twist

Electron fluctuations could explain why exotic material conducts without resistance

1:31pm, November 19, 2008

Sometimes a twist might be as good as a jiggle. Or at least, a new study suggests, twisting electrons appear to take the place of jiggling ions in an exotic kind of superconductor.

It’s the first experiment to show that a certain kind of twisting fluctuations among the electrons in the material could explain its superconductivity, scientists report in the Nov. 20 Nature. The research also supports a 20-year-old theory about how such twists in the spin axes of electrons in general could enable superconductivity for some materials.
