Dynamics of the order parameter of superfluid phases of helium-3

The spin dynamics and the orbital dynamics in the A and B phases of superfluid $^3$ He are analyzed. Attention is focused on solitons and instantons: nonsingular configurations of the field of the order parameter of the $^3$ He superfluid phases. A qualitative explanation in terms of solitons and instantons is offered for several experiments involving the A and B phases of $^3$ He. The analysis of these questions is prefaced by some general information on the order parameter and the free energy in superfluid $^3$ He.
