Abstract
We discuss Coulomb fluids (systems of-particles interacting through Coulomb’s law, plus perhaps some short-range interaction) in the framework of classical equilibrium statistical mechanics. Coulomb fluids exhibit the fundamental property of screening, Screening means that a charge q introduced into the fluid induces a polarization cloud of charge -q, and therefore the excess charge distribution (defined as the sum of the external charge distribution and the induced one) has zero total charge. More generally, all the electrical moments of the excess charge distribution vanish1,2 provided the charge correlations in the fluid have good decay properties at long distances. We do not attempt here to derive screening from first principles, but we take it for granted.
