ON THE THEORY OF THE B-PHASE FOR A FERMI SUPERFLUID WITH TRIPLET COUPLING

The thermodynamic and hydrodynamic equations for a Fermi superfluid wi th triplet coupling are derived. Parameters such as the superfluid pha se and the orthogonal rotation matrix in abridged descriptions are rep resented in terms of the order parameter. The theorem about the connec tion between the flow densities of additive integrals of motion is gen eralized to the case of local equilibrium. Galilean and Lorentz-invari ant physical systems are considered in detail. For the Fermi superflui d under study, the spectra of collective excitations are obtained.
