We propose a lattice statistical model to investigate the phase diagrams and the soft responses of nematic liquid-crystal elastomers. Using suitably scaled infinite-range interactions, we obtain exact self-consistent equations for the tensor components of the nematic order parameter in terms of temperature, the distortion and stress tensors, and the initial nematic order. These equations are amenable to simple numerical calculations, which are used to characterize the low-temperature soft…

Uniaxial and biaxial structures in the elastic Maier-Saupe model.
Analysis of the global phase diagram of a fully connected version of a Maier-Saupe-Zwanzig lattice model with the inclusion of couplings to an elastic strain field finds a first-order boundary along which there is a coexistence of two uniaxial paranematic phases, and which ends at a simple critical point.


Phase diagrams of semisoft nematic elastomers.
The global phase diagram for a minimal model is calculated, and it is shown that semisoft behavior is associated with a broken symmetry biaxial phase and that it persists well into the supercritical regime.
Nonlocal model for nematic liquid-crystal elastomers.
A fully nonlocal model to describe the dynamic behavior of nematic liquid-crystal elastomers and examines the free energy and the equations of motion in the limit of long-wavelength and small-amplitude variations of the displacement and the orientational order parameter.
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.
Isotropic-nematic transition in liquid-crystalline elastomers: lattice model with quenched disorder.
A lattice model of liquid-crystalline elastomers, with local directors coupled to a global strain variable, shows that both types of disorder cause the first-order isotropic-nematic transition to broaden into a smooth crossover, consistent with the experiments.
Nematic elastomers: from a microscopic model to macroscopic elasticity theory.
These phenomenological theories of elasticity are derived from a microscopic model and it is demonstrated that they are universal mean-field descriptions of the elasticity for all chemical gels and vulcanized media.
Semisoft elasticity and director reorientation in stretched sheets of nematic elastomers.
A two-dimensional effective model for the semisoft elastic behavior of nematic elastomers is derived in the thin film limit and an analytical model for their dependence on the aspect ratio of the sample is presented.
Enhancement of Nematic Order and Global Phase Diagram of a Lattice Model for Coupled Nematic Systems
We use an infinite-range Maier–Saupe model, with two sets of local quadrupolar variables and restricted orientations, to investigate the global phase diagram of a coupled system of two nematic
Main-chain swollen liquid crystal elastomers: a molecular simulation study
We have performed large-scale off-lattice computer simulations in a model system of swollen main-chain liquid-crystalline elastomers, constituted of weakly reticulated soft Gay–Berne chains,
Modeling and simulation of liquid-crystal elastomers.
A continuum model describing the dynamic behavior of nematic liquid crystal elastomers (LCEs) is considered and a numerical scheme to solve the governing equations is implemented using an implicit-explicit scheme and the Chebyshev polynomial method.
Nematic elastomersA new state of matter
Recent experimental and theoretical work shows that nematic elastomers have a highly mobile director, despite being nominally solid liquid crystals. We review this work and show that such a system
