Domain Growth Kinetics

We study the applicability of parallelized Monte Carlo algorithms to the simulation of domain growth in 2-dim. lattice gas models after a quench into an ordered phase. Conventional parallelized algorithms with KAWASAKI dynamics introduce artificial spatial correlations into the system. However, only if superstructure domains evolve, these correlations will modify the kinetics by influencing the nucleation process and result in a reduced kinetic exponent. Two improved algorithms with slightly reduced degree of parallelism suitable for simulation of superstructure domain growth are presented and discussed.

Diffusion Of Hydrogen

Q2R cellular automata are combined with Kawasaki dynamics to give an Ising ferromagnet with conserved magnetization and conserved energy. In its lattice gas interpretation, it may serve to describe the diffusion of hydrogen ions on the surface of globular proteins. Our computer simulations test to what extent the phase transition at the Curie point is still visible in small 10×10 lattices and t~104.
