Odd-frequency superconductivity in Sr${}_2$RuO${}_4$ measured by Kerr rotation

Abstract

We establish the existence of bulk odd-frequency superconductivity in Sr${}_2$RuO${}_4$ and show that an intrinsic Kerr effect is a direct evidence of this state. We use both general two- and three-orbital models, as well as a realistic tight-binding description of Sr${}_2$RuO${}_4$ to demonstrate that odd-frequency pairing arises due to finite hybridization between different orbitals in the normal state, and is further enhanced by finite inter-orbital pairing.
