Two-Dimensional Coulomb Systems: a Larger Class of Solvable Models

Abstract

Using new methods, we find that a larger class of two-dimensional Coulomb systems are solvable models, in the framework of equilibrium classical statistical mechanics, for the special value Γ = 2 of the coupling constant. One-component plasmas with adsorption sites, one-component plasmas in a periodic background, and plasmas made of two components plus a background are discussed.
