We propose an approach to a multiscale problem in the theory of thermotropic uniaxial nematics based on the method of statistical field theory. This approach enables us to relate the coefficients A, B, C, L_{1}, and L_{2} of the Landau-de Gennes free energy for the isotropic-nematic phase transition to the parameters of a molecular model of uniaxial nematics, which we take to be a lattice gas model of nematogenic molecules interacting via a short-ranged potential. We obtain general constraints…

Theory of Inhomogeneous Calamitic Coulomb Fluids
A field theoretic representation of the classical partition function is derived for a system composed of a mixture of anisotropic and isotropic mobile charges that interact via long range Coulomb and

Abstract In this work, we study how solvent granularity influences the differential electrical capacitance ( C d ) of supercapacitor using aqueous electrolyte and molecular mechanism modulating the
Ordering of adsorbed rigid rods mediated by the Boussinesq interaction on a soft substrate.
It is shown that anisotropic rods exhibit a continuous isotropic-nematic phase transition, driven by orientational interactions between surface deposited rods.


Nematic Liquid Crystals: From Maier-Saupe to a Continuum Theory
We define a continuum energy functional that effectively interpolates between the mean-field Maier-Saupe energy and the continuum Landau-de Gennes energy functional and can describe both spatially
Hard spherocylinders in an anisotropic mean field: A simple model for a nematic liquid crystal
A simple model for a nematic liquid crystal is presented, in which the short‐range intermolecular repulsions are represented by repulsions between hard spherocylinders, and the (anisotropic)
Molecular theory of liquid crystals: application to the nematic phase
A density-functional description of liquid crystals is developed. Formally exact expansions for thermodynamic functions in terms of a direct-correlation function are given. Approximations to the
Molecular-field-theory approach to the Landau theory of liquid crystals: uniaxial and biaxial nematics.
A Landau theory based on the analogous molecular-field theory for orthorhombic biaxial nematic fluids is constructed, which correctly predicts the complete set of invariants formed from the ordering tensors, and avoids ad hoc parametrization of the molecular biaXiality.
Lattice model for biaxial and uniaxial nematic liquid crystals.
A lattice gas model is used to describe the phase transitions in nematic liquid crystals and displays, in addition to the isotropic phase, the two uniaxial nematics, the rod-like and discotic nematic, and the biaXial nematic.
Simple Molecular Model for the Smectic A Phase of Liquid Crystals
The Maier-Saupe model of the nematic phase with an orientational order parameter is extended to the smectic $A$ phase by introducing a new order parameter, the amplitude of a density wave in the
Isotropic-genesis nematic elastomers (IGNEs) are liquid crystalline polymers (LCPs) that have been randomly, permanently cross-linked in the high-temperature state so as to form an equilibrium random
Generalized van der Waals theory of the isotropic–nematic phase transition
We extend the generalized van der Waals (GVDW) theory to fluids of anisotropic molecules interacting through angle‐dependent potentials which can be broken up into strong short‐ranged repulsions and

It is shown that with better knowledge of the order parameters P − 2 and P − 4 and their temperature and density dependence and the potential parameters appearing in the model, one can calculate accurate values of all the Frank constants of any given system.
