Non-equilibrium phase transition in a binary mixture

Accepted: 22 January 1996
A non-equilibrium phase transition is identified from an exact solution of the Boltzmann equation describing a binary mixture under shear flow in the tracer limit (): there exists a critical value ac (which depends on the mass ratio and the force constant ratios) of the shear rate such that for (disordered phase), while for (ordered phase), where is the relative contribution of the tracer species to the total energy. This phase transition is absent when is sufficiently large and/or the strength of the interactions 2-2 is sufficiently larger than that of 1-2.
