High order nonlinear electrophoresis in a nematic liquid crystal
Mojtaba Rajabi, Taras Turiv, Bing-Xiang Li +3
Electrophoresis is the motion of particles relative to a surrounding fluid driven by a uniform electric field. In conventional electrophoresis, the electrophoretic velocity grows l…
Topological transformations of a nematic drop
Runa Koizumi, Dmitry Golovaty, Ali Alqarni +3
Morphogenesis of living systems involves topological shape transformations which are highly unusual in the inanimate world. Here we demonstrate that a droplet of a nematic liquid c…
Liquid crystal phases with unusual structures and physical properties formed by acute-angle bent-core molecules
Bing-Xiang Li, Yuriy A. Nastishin, Hao Wang +7
Liquid crystals formed by acute-angle bent-core (ABC) molecules with a 1,7 naphthalene central core show an intriguing phase behavior with the nematic phase accompanied by poorly u…
Shear-induced polydomain structures of nematic lyotropic chromonic liquid crystal disodium cromoglycate
Hend Baza, Taras Turiv, Bing-Xiang Li +4
Lyotropic chromonic liquid crystals (LCLCs) represent aqueous dispersions of organic disk-like molecules that form cylindrical aggregates. Despite the growing interest in these mat…
Soliton-induced liquid crystal enabled electrophoresis
Bing-Xiang Li, Rui-Lin Xiao, Sergij V. Shiyanovskii +1
Manipulation of particles by a uniform electric field, known as electrophoresis, is used in a wide array of applications. Of especial interest is electrophoresis driven by an alter…
Three-dimensional solitary waves with electrically tunable direction of propagation in nematics
Bing-Xiang Li, Rui-Lin Xiao, Sathyanarayana Paladugu +2
Production of stable multidimensional solitary waves is a grand challenge in modern science. Steering their propagation is an even harder problem. In this work we demonstrate three…
Microsecond electro-optic switching of nematic liquid crystals with giant dielectric anisotropy
Bing-Xiang Li, Greta Babakhanova, Rui-Lin Xiao +4
Nematic liquid crystals exhibit a fast optical response when the applied electric field modifies the degree of order but does not change the direction of molecular orientation. The…
Dye-doped dual-frequency nematic cells as fast-switching polarization-independent shutters
Bing-Xiang Li, Rui-Lin Xiao, Sathyanarayana Paladugu +2
We present polarization-independent optical shutters with a sub-millisecond switching time. The approach utilizes dual-frequency nematics doped with a dichroic dye. Two nematic cel…
Electrically driven dynamic three-dimensional solitons in nematic liquid crystals
Bing-Xiang Li, Volodymyr Borshch, Rui-Lin Xiao +4
Electric field induced collective reorientation of nematic molecules placed between two flat parallel electrodes is of importance for both fundamental science and practical applica…
Enhanced nanosecond electro-optic effect in isotropic and nematic phases of dielectrically negative nematics doped by strongly polar additive
Bing-Xiang Li, Volodymyr Borshch, Hao Wang +3
An electric field can induce or modify optical birefringence in both the isotropic and nematic phases of liquid crystals (LCs). In the isotropic phase, the electric field induces b…
Kerr effect at high electric field in isotropic phase of mesogenic materials
Bing-Xiang Li, Volodymyr Borshch, Sergij V. Shiyanovskii +2
The well-known Kerr effect in isotropic fluids consists in the appearance of uniaxial orientational order and birefringence that grows as the square of the applied electric field.…
