When Do Like Charges Attract?

Soft Condensed Matter 2015-06-25 v1 Statistical Mechanics

Abstract

We study the interaction potential between two polyions inside a colloidal suspension. It is shown that at large separation the interaction potential is purely repulsive, with the induced attractive interactions being doubly screened. For short separations the condensed counterions become correlated, what leads to an effective attraction between the two macromolecules.
