Spreading of step-like density profiles in interacting lattice gas on a hexagonal lattice

Diffusion in a single-layer adsorbate on a crystalline surface with a hexagonal lattice site symmetry is studied by Monte Carlo simulations. A step-like density profile of the adsorbate is allowed to spread. From the evolution of this density profile the diffusion coefficient is obtained by use of s...
