Algebraic infection of charge correlations at the ionic critical point

We consider a classical two-component plasma analog of the restricted primitive model electrolyte, where hard-core interaction is replaced by soft differentiable potential. Within Born–Green–Yvon hierarchy for equilibrium distribution functions, we shed light on an infection mechanism charge correlations are polluted density at critical point liquid–gas transition. This should imply algebraic decay correlations, consistently with violation Stillinger–Lovett sum rule observed in Monte Carlo simulations. In connection this effect also provide discussion extended version Debye–Hückel theory that calculates externally imposed spatial fluctuation charges. PACS Numbers: 05.30.-d, 05.70.Ce, 52.25.Kn.
