Thermodynamic Properties of the Two-Dimensional Two-Component Plasma

Abstract

The model under consideration is a two-dimensional two-component plasma, stable against collapse for the dimensionless coupling constant $\beta <2$. The combination of a technique of renormalized Mayer expansion with the mapping onto the sine-Gordon theory provides the full thermodynamics of the plasma in the whole stability range of $\beta$. The explicit forms of the density-fugacity relationship and of the specific heat (at constant volume) per particle are presented.
