Hidden anomalous Hall effect in Sr${}_2$RuO${}_4$ with chiral superconductivity dominated by the Ru $d_{xy}$ orbital

Jia-Long Zhang, Yu Li, Wen Huang +1

The polar Kerr effect in superconducting Sr${}_2$RuO${}_4$ implies finite ac anomalous Hall conductivity. Since intrinsic anomalous Hall effect (AHE) is not expected for a chiral super…
