Raman Spectra of Triplet Superconductor in Sr${}_2$RuO${}_4$

Abstract

We study the Raman spectra of spin-triplet superconductors in Sr${}_2$RuO${}_4$. The p-wave and f-wave symmetries are considered. We show that there is the clapping mode with frequency of $\sqrt{2}\Delta (T)$ and $1.02\Delta (T)$ for p-wave and f-wave superconductors, respectively. This mode is visible as a huge resonance in the B1g and B2g modes of Raman spectra. We discuss the details of the Raman spectra in these superconducting states.
