✦ Synopsis


The possible forms of the energy gap as a function of superflow are found and verified by the free energy evaluations for two-dimensional S-paired Fermi systems. The influence of the Fermi liquid corrections on critical behaviour of such systems is discussed, in detail, at zero-temperature limit. It is argued that the tricritical point is reached when the Fermi liquid interaction is excluded. Thus, the diamagnetic instability phenomenon should be observed for a bare-particle system. The obtained results can be applied to new generation superconductors, or to low-concentration superfluid 3He-4He mixtures.
