A system of monosized hard spheres is studied to elucidate the nature of entropic depletion forces. Our calculations include effective forces between two spheres, a hard sphere and a wall, and the behavior near a step edge and a corner. Qualitative differences between our results and those of the Asakura-Oosawa theory are found. We also demonstrate the nonadditivity of such entropic forces in a simple example.

Abstract
A system of monosized hard spheres is studied to elucidate the nature of entropic depletion forces. Our calculations include effective forces between two spheres, a hard sphere and a wall, and the behavior near a step edge and a corner. Qualitative differences between our results and those of the Asakura-Oosawa theory are found. We also demonstrate the nonadditivity of such entropic forces in a simple example.
