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
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.
Journal ArticleDOI
Electrooptic, pyroelectric and dielectric spectroscopic studies of nematic and twist bend nematic phases of achiral hockey-shaped bent-core Liquid Crystal
TL;DR: In this article , a hockey-shaped achiral rigid bent-core LC, called BCI, is investigated for a planar and homeotropic aligned cells, using polarizing optical microscopy, electro-optics, pyroelectricity and wide band dielectric spectroscopy.
Polar nature of the ferro-electric nematic studied by dielectric spectroscopy
TL;DR: Panarin et al. as discussed by the authors studied the nematic-nematic transitions in homogeneously planar and homeotropic aligned cells using dielectric spectroscopy in the frequency range 0.1 Hz to 10 MHz over a wide range of temperatures.
Journal ArticleDOI
Unexpected electric-field-induced antiferroelectric liquid crystal phase in the Sm C*α temperature range and the discrete flexoelectric effect
Yoichi Takanishi,Atsuo Iida,Neelam Yadav,A. D. L. Chandani Perera,Atsuo Fukuda,Mikhail A. Osipov,Jagdish K. Vij +6 more
TL;DR: It is established that an applied field unexpectedly stabilizes the well-known antiferroelectric four-layer biaxial subphase as well as the other prototypal ferrielectric three-layer one in the SmC_{α}^{*} temperature range.
