چکیده
2014 We predict the occurrence of an oscillatory convective instability when a planar texture of cholesteric or smectic A liquid crystals is heated from below. J. P/nBs/~ LETTRES 41 (1980) L-383 L-386 15 AO(J’T 1980,

torting the helical structure of the phase) and the nematic phase develops when the equilibrium pitch of the cholesteric phase becomes larger than the sample thick ness. This transition is first order and can easily be observed when approaching a smectic phase, because the cholesteric pitch diverges at this transition. In this way, it is possible to observe the growth of the cholesteric phase ...
متن کاملParticle-stabilized defect gel in cholesteric liquid crystals
Dispersions of colloidal particles in cholesteric liquid crystals form an unusual solid by stabilizing a network of linear defects under tension in the ideal layered structure of the cholesteric. The large length scales of the cholesteric liquid crystals allowed direct observation of the network structure, and its properties were correlated with rheological measurements of elasticity. This syst...
متن کاملGeneralization of Meyer’s ferroelectricity to cholesteric phase : electroclinic coupling and prediction of a new ferrocholesteric phase
We present a generalization of Meyer's theory of the trilinear coupling between the smectic layers, the tilt angle of the optical axis with respect to the layer normal and the electric polarization which accounts for the spontaneous ferroelectricity in smectic C* liquid crystals. This coupling allows for the description of the electroclinic effect, I-ethe appearance of a polarization and a tilt...

This book is a follow up to the volume Nematics and Cholesteric Liquid Crystals by the same authors in the Liquid Crystal Book Series edited by G.W. Gray, J.W. Goodby and A. Fukuda. Here, the authors, two well known experts from the Ecole Normale Supérieure, Lyon and the Université Paris-Sud, deal with liquid crystalline phases endowed with long range positional order in one or more dimensions,...
متن کاملParabolic focal conics and polygonal textures in lipid liquid crystals
2014 Polygonal defect arrays in lipid liquid crystals prepared from dipalmitoyl-, dimyristoyl-, and dilaurylphosphatidylcholine with various concentrations of water have been observed and characterized using optical microscopy. These arrays appear similar to the polygonal arrays previously observed in thermotropic smectic and cholesteric liquid crystals. The parabolic focal conic model proposed...
