Superfluidity of Liquid He3

Superfluid properties of the A phas(! of the liquid He ' is discussed by assuming "the superfluid state to be the equal spin pairing of the triplet P pairing. The Ginzburg-Landau equations are given valid to the third order terms in the order parameters and to the second order terms i ~ the spatial derivatives. They are solved for the uniform flow and vortex states. Most of discussion is devoted to the bulk systems. The superfluid density has a tensor character and brings about correlations of the flow direction or the vortex axis to the symmetry axis of 'the pair wave function. Inclusion of the paramagnon effect does not change the main results stated here.
