abstract = {Test-area deformations are used to analyze vapor-liquid interfaces of Lennard-Jones particles by
molecular dynamics simulation. For planar vapor-liquid interfaces the change in free energy is
captured by the average of the corresponding change in energy, the leading-order contribution. This
is consistent with the commonly used mechanical  pressure-tensor  route for the surface tension. By
contrast for liquid drops, one finds a large second-order contribution associated with fluctuations in
energy. Both the first- and second-order terms make comparable contributions, invalidating the
mechanical relation for the surface tension of small drops. The latter is seen to increase above the
planar value for drop radii of  8 particle diameters, followed by an apparent weak maximum and
slow decay to the planar limit, consistent with a small negative Tolman length.},
