Asymptotic properties of bridging transitions in sinusoidally-shaped slits
Original language description
We study bridging transitions that emerge between two sinusoidally-shaped walls of amplitude A, wavenumber k, and mean separation L. The focus is on weakly corrugated walls to examine the properties of bridging transitions in the limit when the walls become flat. The reduction of walls roughness can be achieved in two ways which we show differ qualitatively: a) By decreasing k, (i.e., by increasing the system wavelength), which induces a continuous phenomenon associated with the growth of bridging films concentrated near the system necks, the thickness of with the thickness of these films diverging as ~ k−2/3 in the limit of k ! 0. Simultaneously, the location of the transition approaches that of capillary condensation in an infinite planar slit of an appropriatewidth as ~ k2/3, b) in contrast, the limit of vanishing walls roughness by reducing A cannot be considered in this context, as there exists a minimal value Amin(k,L) of the amplitude below which bridging transition does not occur. On the other hand, for amplitudes A > Amin(k,L), the bridgingntransition always precedes global condensation in the system. These predictions, including the scaling property Amin / kL2, are verified numerically using density functional theory.
