In particular, the candidate chiral p-wave order parameter in the momentum space exhibits k-dependence phase winding which is characteristic of time-reversal symmetry breaking.
However, scanning probes have so far failed to detect expected time-reversal symmetry breaking fields generated by the supercurrent, off by orders of magnitude.
However, this naive reasoning was later found not to be entirely correct: the magnitude of edge current is not directly related to the topological property of the chiral state.
[8][9] Tc seems to increase under uniaxial compression[10] that pushes the van Hove singularity of the dxy orbital across the Fermi level.
[14][15] Strontium ruthenate behaves as a conventional Fermi liquid at temperatures below 25 K.[16] In 2023, a team of researchers from the University of Illinois Urbana-Champaign confirmed the 67-year-old prediction of Pines' demon excitation in Sr2RuO4.
