The non-equilibrium self-consistent generalized Langevin equation theory of irreversible relaxation [P. E. Ramŕez-González and M. Medina-Noyola, Phys. Rev. E 82, 061503 (2010); 82, 061504 (2010)] is applied to the description of the non-equilibrium processes involved in the spinodal decomposition of suddenly and deeply quenched simple liquids. For model liquids with hard-sphere plus attractive ...

The theory of phase separation m a liquid crystal by spinodal decompoSit1on is developed The time evolution of two coupled parameters, the volume concentration (or mole fraction), and the orientational order parameter is calculated The conditions for penodic fluctuations are gJven and the structure factor for spinodal decomposition is studied

The initial stage of isotropic-nematic spinodal demixing kinetics of suspensions of very long and thin, stiff, repulsive rods is analyzed on the basis of the N-particle Smoluchowski equation. Equations of motion for the reduced probability density function of the position and orientation of a rod are expanded up to second order in spatial gradients and leading order in orientational order param...

We present simulations of isothermal liquid-vapor spinodal decomposition of a van der Waals fluid, occurring after quenching it from a single-phase equilibrium state to the unsteady two-phase region of its phase diagram, showing that the process is governed by the density gradient-driven, non-equilibrium Korteweg body force. Experimentally, most studies on spinodal decomposition have been perfo...
