'Dancing' two-dimensional patterns in nematics above the flexoelectric instability threshold
E. S. Pikina
Various types of electrohydrodynamic instabilities in liquid crystals (LCs) are a recurring theme in LC research. The nonlinear stage of the flexoelectric instability in nematics r…
Pattern formation in nonlinear dynamics of nematic liquid crystals above the flexoelectric instability threshold
E. S. Pikina, E. I. Kats, A. R. Muratov +1
For many decades, researchers have been studying various types of electro-hydrodynamic instabilities in liquid crystals. A significant amount of experimental data has been collecte…
Dynamic flexoelectric instabilities in nematic liquid crystals
E. S. Pikina, A. R. Muratov, E. I. Kats +1
Electro-hydrodynamic phenomena in liquid crystals constitute an old but still very active research area. The reason is that these phenomena play the key role in various application…
Marangoni instability in oblate droplets suspended on a circular frame
M. A. Shishkin, K. S. Kolegov, S. A. Pikin +2
We study theoretically internal flows in a small oblate droplet suspended on the circular frame. Marangoni convection arises due to a vertical temperature gradient across the drop…
Nonlinear electro-hydrodynamics of liquid crystals
E. S. Pikina, E. I. Kats, A. R. Muratov +1
We present nonlinear dynamic equations for nematic and smectic liquid crystals in the presence of an alternating electric field and explain their derivation in detail. The loca…
Circulating Marangoni flows within droplets in smectic films
E. S. Pikina, M. A. Shishkin, K. S. Kolegov +2
We present theoretical study and numerical simulation of Marangoni convection within ellipsoidal isotropic droplets embedded in free standing smectic films (FSSF). The thermocapill…
Long-range interactions between membrane inclusions: Electric field induced giant amplification of the pairwise potential
E. S. Pikina, A. R. Muratov, E. I. Kats +1
The aim of this work is to revisit the phenomenological theory of the interaction between membrane inclusions, mediated by the membrane fluctuations. We consider the case where the…
Evidence of a first-order smectic -- hexatic transition and its proximity to tricritical point in smectic films
Ivan A. Zaluzhnyy, Ruslan P. Kurta, Nastasia Mukharamova +10
Experimental and theoretical studies of a smectic-hexatic transition in freely suspended films of 54COOBC compound are presented. X-ray investigations revealed a discontinuous firs…
