The Asakura-Oosawa model in the protein limit: the role of many-body interactions
arXiv:cond-mat/0309283 · doi:10.1088/0953-8984/15/48/004
Abstract
We study the Asakura-Oosawa model in the "protein limit", where the penetrable sphere radius $R_{AO}$ is much greater than the hard sphere radius $R_c$. 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.
