Effects of the dipole interaction in superfluid B3

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.
