The phase equilibria of a lattice gas confined two parallel walls are investigated in mean-field approximation. Only a finite number of the first-order layering transitions, characteristic of the adsorption isotherms π(μ) for a strongly attractive substrate, survive when the wall- separation H...

We consider the equilibrium properties of a simple one-dimensional model for a colloid–polymer mixture in which the colloids are modelled by hard rods and the polymers are treated as ideal particles excluded from the colloids by a certain distance. By mapping the binary mixture to an effective...
