Two-dimensional superfluid Fermi liquid with p-pairing

The axial and planar phases of the two-dimensional superfluid Fermi liquid are discussed. The difference between the free energies of these phases is calculated with corrections for strong coupling at arbitrary temperature. The sign of this difference turns out to be temperature-independent in this approximation. Phase transitions occurring in the axial and planar phases as the temperature is increased, and the structure of ordered states, are investigated. Ordering is examined with allowance for the spin-orbit interaction. A schematic phase diagram is constructed
