Using the liquid state thermodynamic perturbation theory and the hard-sphere fluid as the reference system, the liquid–glass transition line of Lennard–Jones and hard-core Yukawa fluids is computed. The results are presented both in the reduced density vs. reduced temperature and in the...

We consider a region bounded by two conductors held to a constant voltage bias, one of them with an irregular rough shape and the other being a flat one. The irregular profile can be either a curve with a formation rule or the result of a deposition process. The rough shape of the profile...

With the proposal by H.E. Stanley and coworkers and the late G.W. Robinson and his coworkers that liquid water exists as two rapidly exchanging microdomains of different densities, the already complex living cell has acquired new levels of complexity. Microdomains are apparently of the order of...

In the framework of SOS models, the dynamics of isolated and pairs of surface steps of monoatomic height is studied, for step–edge diffusion and for evaporation kinetics, using Monte Carlo techniques. In particular, various interesting crossover phenomena are identified. Simulational results...
