Computer simulation of mass transport in a driven diffusive system

Research output: Contribution to journalJournal articleResearchpeer-review

Monte Carlo computer-simulation techniques are applied to study the mass-density profile and the mass flux in a two-dimensional lattice-gas model driven by a chemical-potential gradient. The collective diffusion constant is calculated and shown to have a dramatic temperature dependence with an anomalous depression at the non-equilibrium phase transition of the model. For large values of the chemical potential gradient the driven system is found to undergo a phase-separation process.
