    Filling transitions in acute and open wedges

  • Original language description

    We present numerical studies of first-order and continuous filling transitions in wedges of arbitrary opening angle psi, using a microscopic fundamental measure density functional model with short-ranged fluid-fluid forces and long-ranged wall-fluid forces. In this system the wetting transition characteristic of the planar wall-fluid interface is always first order regardless of the strength of the wall-fluid potential epsilon(omega). In the wedge geometry, however, the order of the filling transition depends not only on epsilon(omega) but also on the opening angle psi. In particular we show that even if the wetting transition is strongly first order the filling transition is continuous for sufficient acute wedges. We show further that the change in the order of the transition occurs via a tricritical point as opposed to a critical end point. These results extend previous effective Hamiltonian predictions which were limited only to shallow wedges.
