Hydrodynamic Correlation Functions in Nematic Liquid Crystals

چکیده
Résumé. — L'objet du présent article consiste en un réexamen du résultat suivant récemment obtenu par Forster : dans le cas des cristaux liquides nématiques, il n'est pas possible de déterminer de manière complète, à partir de la matrice hydrodynamique, les amplitudes liées à tous les modes diffusifs. Nous montrons qu'à partir des lois de symétrie d'inversion spatiale et d'inversion de temps, ces amplitudes peuvent être exprimées en termes de trois constantes indéterminées.

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 کاملStatic and Hydrodynamic Properties of Nematic Liquid Crystals *
The static properties of nematic liquid crystals are summarized. The mean field potential emerging from the static distribution function has been used to the hydrodynamic theory. Rotational viscosity coefficients have been investigated. The Parodi relation has been shown to be completely satisfied. Static and hydrodynamic properties have been predicted on the basis of one intermolecular potential.
متن کاملElectroconvection in Nematic Liquid Crystals: Comparison between Experimental Results and the Hydrodynamic Model
We describe experimental observations illustrating the extraordinary sensitivity of pattern formation in electroconvection in nematic liquid crystals to changes in magnitude and sign of dynamic transport coe cients triggered by weak uctuations from a lower temperature nematic-smectic A phase transition. These results are compared to predictions of a hydrodynamic model (HM). We nd two patterns a...
متن کاملWell-posedness of Nematic Liquid Crystal Flow
In this paper, we establish the local well-posedness for the Cauchy problem of the simplified version of hydrodynamic flow of nematic liquid crystals (1.1) in R3 for any initial data (u0, d0) having small L3 uloc -norm of (u0,∇d0). Here L3uloc(R 3) is the space of uniformly locally L3-integrable functions. For any initial data (u0, d0) with small ‖(u0,∇d0)‖L3(R3), we show that there exists a un...
متن کاملEnergy Stable Numerical Schemes for a Hydrodynamic Model of Nematic Liquid Crystals
We develop a first-order and a second-order, coupled, energy stable numerical schemes for a modified Ericksen–Leslie hydrodynamic model for nematic liquid crystals. We then discuss two ways to develop decoupled schemes for the model and show that they are energy stable as well. The coupled schemes are implemented in 2-dimensional space, with which we study defect dynamics in flows of nematic li...
