Relations between Nematic Potential and Order Parameters ( P 2 ) and ( P
نویسنده
چکیده
The Maier-Saupe theory is employed in order to calculate order parameters (P 2 ) , (P4) f rom the nematic potential q. The relation between <r=q/(RT) and S = (P2) corresponds well with a recently established formula by Kalmykov. The relation between the order parameters is in accordance with the analytic expression (P4)=5/l (P2) proposed by Zanonni, but deviates significantly f rom the Faber model, according to which log (P 4 )=(10 /3) log (P2). Experimental results for 5 CB obtained f rom Raman measurements, however, are in better agreement with the Faber model.

Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals
Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...
متن کاملDirector Structures in a Chiral Nematic Slab: Threshold Field and Pitch Variations
Abstract The liquid crystal director distribution is determined for a confined chiral nematic slab. The molecular director distribution of the field-controlled chiral nematic slab is directly calculated. The director profiles for the tilt and the twist angles, under different applied fields, are calculated in the slab with weak boundary conditions. Then, the dependence of the threshold field on...
متن کاملComputational studies of history dependence in nematic liquid crystals in random environments.
Glassy liquid crystalline systems are expected to show significant history-dependent effects. Two model glassy systems are the RAN and SSS (sprinkled silica spin) lattice models. The RAN model is a Lebwohl-Lasher lattice model with locally coupled nematic spins, together with uncorrelated random anisotropy fields at each site, while the SSS model has a finite concentration of impurity spins fro...

متن کاملGlass Formation in the Gay - Berne nematic liquid crystal
We present the results of molecular dynamics simulations of the Gay-Berne model of liquid crystals, supercooled from the nematic phase. We find a glass transition to a metastable phase with nematic order and frozen translational and orientational degrees of freedom. For fast quench rates the local structure is nematic-like, while for slower quench rates smectic order is present as well. 61.30.-...
