Doublet Splitting and the Low-Field Evolution of the Real Squashing Modes in Superfluid ³He-B

Abstract:

We consider the effects of textures on the collective-mode spectrum of ³He. Our result for the frequency splitting of the real-squashing-mode doublet agrees well with the measurements of Shivaram et al. The smooth disappearance of the doublet and the nonlinear evolution of the real-squashing-mode frequencies at low magnetic fields are explained in terms of a crossover to the dispersion-dominated regime when (qv_f)²/Δ > γ H.
