Query: Depletion interaction between two ellipsoids   The depletion interactions between two ellipsoids in three configurations
were studied by both Monte Carlo simulation with the Wang-Landau algorithm and
the density functional theory in the curvature expansion approximation. Common
features of the depletion interactions were found and the results were as
expected. By comparing the results of the two methods, it is concluded that
density functional theory under the curvature expansion approximation gave very
good results to the depletion forces.
