We investigate spherical macroions in the strong Coulomb coupling regime within the primitive model in salt-free environment. We first show that the ground state of an isolated colloid is naturally overcharged by simple electrostatic arguments illustrated by the Gillespie rule. We furthermore demonstrate that in the strong Coulomb coupling this mechanism leads to ionized states and thus to long range attractions between like-charged spheres. We use molecular dynamics simulations to study in…

Electrostatic correlations in colloidal suspensions: density profiles and effective charges beyond the Poisson-Boltzmann theory.
A theory is proposed which allows to accurately calculate the osmotic pressure and the effective charge of colloidal particles with multivalent counterions around a colloidal particle using the cell model.
Interplay between Depletion and Electrostatic Interactions in Polyelectrolyte–Nanoparticle Systems
We use a numerical implementation of polymer self-consistent field theory to study the effective interactions between two spherical particles in polyelectrolyte solutions. We consider a model in
Structure and correlations in two-dimensional classical artificial atoms confined by a Coulomb potential.
The ordering of N equally charged particles (-e) moving in two dimensions and confined by a Coulomb potential, resulting from a displaced positive charge Ze is discussed, and the configurations of charged particles may result in ring structures, hexagonal-type configurations, and for N/Z approximately 1 in an inner structure of particles which is separated by an outer ring of particles.
Like-charge colloid-polyelectrolyte complexation
We investigate the complexation of a highly charged sphere with a long flexible polyelectrolyte, both negatively charged in a salt-free environment. Electroneutrality is insured by the presence of
Correlations and fluctuations of charged colloids as determined by anomalous small-angle X-ray scattering
We performed molecular dynamics simulation of a charged colloidal particle with explicit counterions. Our work provides a direct comparison between simulations and ASAXS-experiments, offering insight

Recent progress in understanding the effect of electrostatics in soft matter is presented, and theoretical and simulational aspects, including the experimental motivations, will be discussed.
The Physics of Overcharging

In this article we review the two basic mechanisms responsible for overcharging a single spherical colloid in the presence of aqueous salts. The first mechanism rests on energetic arguments, and
Density-functional theory of spherical electric double layers and zeta potentials of colloidal particles in restricted-primitive-model electrolyte solutions.
The density-functional theory is able to capture the oscillatory density profiles of small ions and the charge inversion (overcharging) phenomena for particles with elevated charge density, and predicts the formation of a second counterion layer near the surface of highly charged spherical particle.
