Predictions indicate that certain nodal superconductors with broken time-reversal symmetry have Fermi surfaces made up of charge-neutral broken Cooper pairs. This is a departure from earlier theory that accounted for the electronic structure of these superconductors via point or line nodes of the superconducting gap.
