Microscopic Model for Thin Film Spreading [PDF]
Physical Review Letters, 2002 A microscopic, driven lattice gas model is proposed for the dynamics and spatio-temporal fluctuations of the precursor film observed in spreading experiments. Matter is transported both by holes and particles, and the distribution of each can be described by driven diffusion with a moving boundary.

Microscopic realizations of the trap model [PDF]
Journal of Physics A: Mathematical and General, 2004 Monte Carlo optimizations of Number Partitioning and of Diophantine approximations are microscopic realizations of `Trap Model' dynamics. This offers a fresh look at the physics behind this model, and points at other situations in which it may apply.
