The influence of an external magnetic field and anisotropy on the “charge” Q(t, x) = div vs in 3He---A

The normalization condition AijAij = 1 for the matrix order parameter describing 3He---A leads to the relation , where denotes the equation of motion for Aij. It was shown that this relation is a condition for superfluid velocity vs of the form div vs = Q(t, x). If in the system the correlations and nonlocal dependences are important the “charge” Q(t, x) depends on the part of the density of magnetization m connected with the diffusive anisotropic mode and on an external magnetic field H.
