Supersymmetry model of a binary mixture with noise of the diffusion flux

Supersymmetry theory of diffusion is elaborated to study analytically a non-equilibrium binary mixture with relaxation of diffusion flux. Within such a scheme, Bose components represent order parameter and amplitude of fluctuations of the diffusion flux, while the mutually conjugated combination of Fermi-components gives the mixture concentration. For above variables, the system of equations is found to describe self-consistent behavior of a binary mixture, when the shortest observable time interval is longer than the flux relaxation time.
