The scientists have seen unexpected things in supercurrents—electricity that moves through materials without resistance, usually at super cold temperatures—that break symmetry and are supposed to be forbidden by the conventional laws of physics, said Jigang Wang, a professor of physics and astronomy at Iowa State University, a senior scientist at the U.S. Department of Energy's Ames Laboratory and the leader of the project. "The forbidden light gives us access to an exotic class of quantum phenomena—that's the energy and particles at the small scale of atoms—called forbidden Anderson pseudo-spin precessions," Perakis said. ... Wang's recent studies have been made possible...
