Possible f-wave superconductivity in Sr${}_2$RuO${}_4$?

Abstract

Until recently it has been believed that the superconductivity in Sr${}_2$RuO${}_4$ is described by p-wave pairing. However, both the recent specific heat and the magnetic penetration depth measurements on the purest single crystals of Sr${}_2$RuO${}_4$ appear to be explained more consistently in terms of f-wave superconductivity. In order to further this hypothesis, we study theoretically the thermodynamics and thermal conductivity of f-wave superconductors in a planar magnetic field. We find the simple expressions for these quantities when $H\ll H_{c2}$ and $T\ll T_c$, which should be readily accessible experimentally.
