Abstract

We have studied the phase diagrams of the system of hard ellipsoids in special circumstances based on the Parsons-Lee theory. In the applied external field, we have found that zero field isotropic-nematic phase transition is replaced by a weakly ordered nematic-nematic phase equilibrium. The increasing strength of external field shifts the phase transition in the direction of lower densities and narrows the density gap ending the first order transition at a critical point. The phase diagrams of the hard ellipsoids in a round hole potential are very varied, besides the usual vapour-liquid-nematic transitions we have located a nematic-nematic phase coexistence as well. The results of the theory show good agreement with the correspondig simulation data.
