Unexpected behavior in a tunneling experiment on one of the high‐temperature superconductors has led the experimenters to conclude that they are seeing broken time‐reversal symmetry. The evidence, if confirmed, would indicate a violation of time reversal only at the surface, but it nevertheless has created a lot of interest, especially among theorists who predicted some type of symmetry breaking in unconventional superconductors even in the bulk.
