'Broken symmetry' discovery in high-temperature superconductors opens new research path

In a major step toward understanding the mysterious 'pseudogap' state in high-temperature cuprate superconductors, a team of Cornell, Binghamton University and Brookhaven National Laboratory scientists have found a 'broken symmetry,' where electrons act like molecules in a liquid crystal: Electrons between copper and oxygen atoms arrange themselves differently 'north-south' than 'east-west'...
