Exotic electrostatics in soft matter : from weak to strong coupling

We present an overview of our current understanding of the interactions between like-charged macro-molecules, mediated by mobile neutralizing counter-ions. A single dimensionless parameter qualifies the regime as weakly or strongly coupled, and drives qualitatively different features with the possibility of strong attraction between like-charged colloids. Particular emphasis will be put on a recently introduced strong coupling expansion.
