Charge inversion in colloidal systems
Rene Messina, Christian Holm, Kurt Kremer
Abstract
We investigate spherical macroions in the strong Coulomb coupling regime within the primitive model in salt-free environment. Molecular dynamics (MD) simulations are used to elucidate the effect of discrete macroion charge distribution on charge inversion. A systematic comparison is made with the charge inversion obtained in the conventional continuous charge distribution. Furthermore the effect of multivalent counterions is reported.
