A mapping between the first few virial coefficients of the binary nonadditive hard-sphere mixture representative of this model and those arising from the coarse-grained (pairwise) depletion potential approximation allows for a quantitative evaluation of the effect of such interactions. This turns out to be especially important for large size ratios and large reservoir polymer packing fractions.","authors_text":"Andr\\'es Santos, Franz Saija, Giacomo Fiumara, Mariano L\\'opez de Haro","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2015-03-23T12:08:09Z","title":"The effective colloid interaction in the Asakura-Oosawa model.
