Ultra-Thin Nanowires Can Trap Electron ‘Twisters’ That Disrupt Superconductors

Superconductor materials are prized for their ability to carry an electric current without resistance, but this valuable trait can be crippled or lost when electrons swirl into tiny tornado-like formations called vortices. To keep supercurrents flowing at top speed, Johns Hopkins scientists have figured out how to constrain troublesome vortices by trapping them within extremely short, ultra-thin nanowires.

$2.2 million will help physicist explore exotic materials

N. Peter Armitage of the Institute for Quantum Matter and the Henry A. Rowland Department of Physics and Astronomy at the Johns Hopkins University’s Krieger School of Arts and Sciences has received a $2.2 million grant from the Gordon and Betty Moore Foundation to invent and develop new optical techniques and instruments to explore the characteristics of complex condensed matter such as superconductors, electronic gases and quantum magnets.
