New understanding of superconductor’s ‘normal’ state may open the way to solving longstanding puzzle

Since the discovery two decades ago of the unconventional topological superconductor Sr2RuO4, scientists have extensively investigated its properties at temperatures below its 1°K critical temperature (Tc), at which a phase transition from a metal to superconducting state occurs. Now experiments done at the University of Illinois at Urbana-Champaign in the Madhavan and Abbamonte laboratories, in … Read more
