Abstract

The effects of the dipole interaction on the equilibrium and nonequilibrium properties of B3 are calculated using the quasiclassical theory. In zero field, the dipole interaction distorts the l=1 gap, generates an l=3 gap, and induces a new rotated planar phase next to the normal-state transition. The field dependence of the Leggett angle L is calculated to order (H/)2, including the effect of nonquasiparticle corrections. Using the equilibrium properties as input, we calculate the zero-field NMR frequencies in the collisionless regime. A calculation of the field dependence of the longitudinal NMR frequency reveals the existence of a Fermi-liquid oscillation term due to the out-of-phase motion of the normal and superfluid components. Finally, we compare the collisionless and hydrodynamic theories of NMR.
