Criticality in strongly correlated fluids

In this brief review I will discuss criticality in strongly correlated fluids. Unlike the molecules of simple fluids, which interact through short-ranged isotropic potentials, particles of strongly correlated fluids usually interact through long-ranged forces of Coulomb or dipolar form. While for simple fluids the mechanism of phase separation into liquid and gas was elucidated by van der Waals more than a century ago, the universality class of strongly correlated fluids, or in some cases even the existence of liquid-gas phase separation, remains uncertain.
