Soliton Propagation in Liquid Crystals

Recent Progresses on Experimental Investigations of Topological and Dissipative Solitons in Liquid Crystals

“…By moving the exciter, propagating director waves were observed through polarized white light as black lines, which travelled through the nematic bulk (Figure 3b). It should be noted that these solitons were first theoretically predicted and explained by Lin et al [24][25][26]. Later, in 1987, C. Q. Shu et al reported the generation of two-dimensional (2D) axisymmetric propagating solitons in a radial Poiseuille flow of homeotropic nematic LCs [27].…”

Electrically driven formation and dynamics of swallow-tail solitons in smectic A liquid crystals

“…Early studies were concentrated on the so-called planar or linear solitons, which are actually transition regions or 'walls' where n smoothly rotates by π 10,11 . Propagating solitary waves were generated in nematics by shearing 12,13 . Optical solitons in nematics called nematicons represent self-focused, continuous wave light beams and have received great attention in the last decade due to their promising applications in optical information technology 14 .…”

Investigation of Liquid Crystal Ripple Using Ericksen-Leslie Theory for Displays Subject to Tactile Force

“…Brochard et al [4] investigated transient distortions in a nematic film by increasing or decreasing of the magnetic field. Lei et al [5] used the Ericksen-Leslie equation to describe soliton propagation in nematic liquid crystals under shear. Leslie [6] presented a concise but clear derivation of continuum equations commonly employed to describe static and dynamic phenomena in nematic liquid crystals.…”

“…Comparing different LC materials including 5CB, MBBA, and PAA subjected to 10 ms duration tactile forces of 1 dyne, 0.5 dyne, and 0.1 dyne at 10 ms,Figures 3,4,and 5 show that a larger force makes the tilt angle larger regardless of LC gap thickness. Figures 6(a), 6(b), and 6(c) compare 3 m thick different LC materials including 5CB, MBBA, and PAA subjected to 5 ms duration 0.5 dyne force, respectively.…”
