Lines of invariant physics in the isotropic phase of the discotic Gay-Berne model

The Gay-Berne model is studied numerically with a choice of parameters allowing for the formation discotic liquid crystal at low temperatures. We show that has strong virial potential-energy correlations in isotropic phase high temperatures, i.e., it obeys criterion existence isomorphs, which are curves approximately invariant structure and dynamics. These properties demonstrated to be reduced units along isomorph studied. described well by constant density-scaling exponent 11.5, number significantly larger than exponents various Lennard-Jones models always below 6.
