  We introduce a mean-field model for the potential energy landscape of a thin
fluid film confined between parallel substrates. The model predicts how the
number of accessible basins on the energy landscape and, consequently, the
film's ideal glass transition temperature depend on bulk pressure, film
thickness, and the strength of the fluid-fluid and fluid-substrate
interactions. The predictions are in qualitative agreement with the
experimental trends for the kinetic glass transition temperature of thin films,
suggesting the utility of landscape-based approaches for studying the behavior
of confined fluids.
