We consider a simple Maier-Saupe statistical model with the inclusion of disorder degrees of freedom to mimic the phase diagram of a mixture of rodlike and disklike molecules. A quenched distribution of shapes leads to a phase diagram with two uniaxial and a biaxial nematic structure. A thermalized distribution, however, which is more adequate to liquid mixtures, precludes the stability of this biaxial phase. We then use a two-temperature formalism, and assume a separation of relaxation times…

Biaxial nematic phase in the Maier-Saupe model for a mixture of discs and cylinders
A two-temperature formalism is used to mimic the presence of two distinct relaxation times, and it is shown that a slight departure from complete thermalization is enough to stabilize a biaxial nematic phase.
Elementary lattice models for the nematic transitions in liquid-crystalline systems
ABSTRACT The Maier-Saupe theory of the nematic phase transitions, with the requirement that the molecular directors are restricted to the Cartesian axes, can be formulated as a fully-connected

We investigate the connections between some simple Maier-Saupe lattice models, with a discrete choice of orientations of the microscopic directors, and a recent proposal of a two-tensor formalism to
Modulated phases in a three-dimensional Maier-Saupe model with competing interactions.
It is shown that the proposed model exhibits isotropic and nematic phases and also a series of modulated phases that meet at a multicritical point, a Lifshitz point, and Monte Carlo simulations corroborate the general behavior found within the mean-field approximation.
Bimodal form distribution from modelling biaxial lyotropic liquid crystal solutions through a polydisperse Maier–Saupe model
ABSTRACT Biaxial nematic phases have been the subject of a long list of studies. In particular, they were found for a few lyotropic micellar solutions. There is a debate in the literature on whether

A lattice statistical model is proposed to investigate the phase diagrams and the soft responses of nematic liquid-crystal elastomers, finding a peculiar phase diagram, in terms of temperature and the diagonal component of the distortion tensor along the stretching direction, with first- and second-order transitions to the soft phase.
Elastic Maier-Saupe-Zwanzig model and some properties of nematic elastomers.
A simple mean-field lattice model to describe the behavior of nematic elastomers is introduced, and it is shown that random fields may soften the first-order transition between nematic and isotropic phases, provided the samples are formed in the nematic state.

We use a simple statistical model to investigate the effects of an applied magnetic field and of the dilution of site elements on the phase diagrams of biaxial nematic systems, with an emphasis on
