CHAMPAIGN, Ill. -- Recent experiments on yttrium-barium-copper-oxide (YBCO) superconductors have generated a clearer understanding of the peculiar behavior of this unconventional material. Most significant among the findings, by studying a characteristic called the zero-bias conductance peak, scientists at the University of Illinois -- working with scientists at Northwestern University -- have discovered the first example of a solid superconductor displaying broken time-reversal symmetry.
