Exact solution of a phase-separation model with conserved-order-parameter dynamics and arbitrary initial concentration.
Pairwise particle-exchange model on a linear lattice is solved exactly by a new rate-equation method. Lattice sites are occupied by particles A and B which can exchange irreversibly provided the local energy in reduced. Thus, the model corresponds to a zero-temperature Kawasaki-type phase separation process. Due to local order-parameter conservation, the dynamics reaches a frozen state at large...
متن کاملGrowth kinetics for a system with a conserved order parameter.
The theory of growth kinetics developed previously is extended to the asym-metric case of oo-critical quenches for systems with a conserved scalar order parameter. In this instance the new parameter M, the average global value of the order parameter, enters the theory. For M = 0 one has critical quenches, while for suuciently large M one approaches the coexistence curve. For all M the theory su...
متن کاملKinetics of Fluid Phase Separation
We review understanding of kinetics of fluid phase separation in various space dimensions. Morphological differences, percolating or disconnected, based on overall composition in a binary liquid or density in a vapor-liquid system, have been pointed out. Depending upon the morphology, various possible mechanisms and corresponding theoretical predictions for domain growth are discussed. On compu...
متن کاملA Lattice Model of Charge-Pattern-Dependent Polyampholyte Phase Separation.
In view of recent intense experimental and theoretical interests in the biophysics of liquid-liquid phase separation (LLPS) of intrinsically disordered proteins (IDPs), heteropolymer models with chain molecules configured as self-avoiding walks on the simple cubic lattice are constructed to study how phase behaviors depend on the sequence of monomers along the chains. To address pertinent gener...
متن کاملKinetics and morphologies of viscoelastic phase separation.
In this paper, the effects of relaxational bulk modulus and the average composition of polymers on the viscoelastic phase separation are investigated in detail. It is found that there are two typical morphologies, i.e., moving droplet phase and phase inversion, and the relaxation of the dynamical asymmetry and the amplification of the concentration fluctuation are responsible for the appearance...
