Physicists uncover new Competing state of matter in Superconducting material

Ames Laboratory researchers used laser pulses of less than a trillionth of a second in much the same way as flash photography, in order to take a series of snapshots. Called terahertz spectroscopy, this technique can be thought of as “laser strobe photography” where many quick images reveal the subtle movement of electron pairings inside the materials using long wavelength far-infrared light.

A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.

“Superconductivity is a str...
