Phase equilibria of size- and charge-asymmetric primitive models of ionic fluids: the method of collective variables

We study the phase diagrams of z:1 size-asymmetric primitive models (PMs) using a theory that exploits the method of collective variables. Based on the explicit expression for the relevant chemical potential (conjugate to the order parameter) which includes the correlation effects up to the third or...
