Diffusion and Thermal Diffusion Influence on Temperature Relaxation in Superfluid 3He-4He Mixtures

Formation of a nonequilibrium stationary state in quantum superfluid He-3-He-4 mixtures is studied in this paper. The problem is considered on a segment with the heat flow switched on at the left end and with the constant temperature at the right end. Second sound mode contribution and dissipative mode contribution is studied. The problem is solved at arbitrary temperatures and concentrations of He-3 and this needs the accounting of diffusion and thermal diffusion processes in superfluid He-3-He-4 mixtures.
