Ionic fluid criticality restricted primitive model

In the absence of a reliable theory, computer simulations have become the most important means of tackling the question of ionic criticality. In the last ten years there have been numerous attempts to identify the universality class of what is perhaps the most basic model of ionic fluids, the restricted primitive model (RPM). The RPM consists of an equimolar mixture of positively and negatively charged hard spheres with diameter a, immersed in a dielectric continuum with dielectric constant D. The pair potential is,... 

In this contribution we have reviewed the results from recent simulations directed towards understanding the manifestation of critical phenomena and finite-size scaling in systems with long-range interactions, including the restricted primitive model of ionic fluids, the charged hard dumbbell fluid, and hard spheres with algebraic interactions. The main conclusions from our studies are as follows.
