Journal ArticleDOI
Chiral smectic-A and smectic-C phases with de Vries characteristics.
Neelam Yadav,Neelam Yadav,Vitaly P. Panov,V. Swaminathan,S. P. Sreenilayam,Jagdish K. Vij,Tatiana S. Perova,Ravindra Dhar,A. Panov,D. Rodriguez-Lojo,Paul J. Stevenson +10 more
TL;DR: The Debye-Langevin model is found to be extremely effective in confirming some of the conclusions of the de Vries chiral smectics and gives additional results on the order parameter and the dichroic ratio as a function of the field across the cell.
Journal ArticleDOI
Design and investigation of de Vries liquid crystals based on 5-phenyl-pyrimidine and (R,R)-2,3-epoxyhexoxy backbone.
S. P. Sreenilayam,D. Rodriguez-Lojo,Vitaly P. Panov,V. Swaminathan,Jagdish K. Vij,Yu. P. Panarin,Ewa Gorecka,A. Panov,Paul J. Stevenson +8 more
TL;DR: A three-parameter mean-field model is introduced for the orientational distribution function (ODF) to reproduce the electro-optic properties and explains the experimental results and leads to the ODF, which exhibits a crossover from the sugar-loaf to diffuse-cone ODF some 3 °C above T_{AC}.
Journal ArticleDOI
Phase behavior and characterization of heptamethyltrisiloxane-based de Vries smectic liquid crystal by electro-optics, x rays, and dielectric spectroscopy.
S. P. Sreenilayam,Dena Mae Agra-Kooijman,Vitaly P. Panov,V. Swaminathan,Jagdish K. Vij,Yu. P. Panarin,Antoni Kocot,A. Panov,D. Rodriguez-Lojo,Paul J. Stevenson,Michael R. Fisch,Satyendra Kumar,Satyendra Kumar +12 more
TL;DR: Observations of a large electroclinic effect, a large increase in the birefringence with electric field, a low shrinkage in the layer thickness, and low values of the reduction factor suggest that the SmA^{*} phase in this material is of the de Vries type.
Journal ArticleDOI
The effect of chiral doping in achiral smectic liquid crystals on the de Vries characteristics: smectic layer thickness, electro-optics and birefringence
V. Swaminathan,Vitaly P. Panov,Yu. P. Panarin,S. P. Sreenilayam,Jagdish K. Vij,A. Panov,D. Rodriguez-Lojo,Paul J. Stevenson,Ewa Gorecka +8 more
TL;DR: In this paper, an addition of chiral dopant to two achiral smectic liquid crystals from a homologous series, by varying weight percentages with known low values of layer shrinkage, leads to a chiral Smectic-C* phase with a finite value of spontaneous polarisation.
Journal ArticleDOI
Observation of the de Vries behavior in SmA* phase of a liquid crystal using polarised Raman scattering and infrared spectroscopy
Antoni Kocot,Jagdish K. Vij,Tatiana S. Perova,K. Merkel,V. Swaminathan,S. P. Sreenilayam,Neelam Yadav,Vitaly P. Panov,Paul J. Stevenson,A. Panov,D. Rodriguez-Lojo +10 more
TL;DR: It is concluded that the "cone-shaped" (or volcano-shaped) de Vries type of distribution can most preferably describe SmA* where "a first-order phase transition fromSmA* to SmC*" and a low layer shrinkage can both be easily explained.
