Abstract

We study the Asakura-Oosawa model in the "protein limit", where the penetrable sphere radius RAO is much greater than the hard sphere radius Rc. The phase behaviour and structure calculated with a full many-body treatment show important qualitative differences when compared to a description based on pair potentials alone. The overall effect of the many-body interactions is repulsive.
