Electromagnetic Response of a kx iky Superconductor: Effect of Order Parameter Collective Modes
S. Higashitani, K. Nagai
Abstract
Effects of order parameter collective modes on electromagnetic response are studied for a clean spin-triplet superconductor with kx iky orbital symmetry, which has been proposed as a candidate pairing symmetry for Sr2RuO4. It is shown that the kx iky superconductor has characteristic massive collective modes analogous to the clapping mode in the A-phase of superfluid 3He. We discuss the contribution from the collective modes to ultrasound attenuation and electromagnetic absorption. We show that in the electromagnetic absorption spectrum the clapping mode gives rise to a resonance peak well below the pair breaking frequency, while the ultrasound attenuation is hardly influenced by the collective excitations.
