DEPOSITION-EVAPORATION STOCHASTIC-SYSTEMS IN 2 AND HIGHER DIMENSIONS

We study the stochastic dynamics of deposition-evaporation cooperative processes of dimers, trimers, etc., in two- and higher-dimensional la ttices. The dimer system in bipartite lattices allows for an exact sol ution of dynamic correlations and scaling functions by means of a quan tum spin equivalence. Autocorrelations exhibit a diffusive asymptotic kinetics and crossovers of different dynamic regimes in highly anisotr opic lattices. Monte Carlo simulations combined with finite-size scali ng arguments support the validity of the diffusive picture in more gen eral situations. Steady-state coverages and diffusion constants are ob tained using mean-field approaches, spin wave calculations, and random walk analyses in nearly jammed configurations.
