Raman spectra of triplet superconductivity in Sr2RuO4

We study the Raman spectra of spin-triplet superconductors in Sr2RuO4. The p-wave and f-wave symmetries are considered. We show that there is the clapping mode with frequency of A2D(T) and D(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.
