Mesoscale structure of wrinkle patterns and defect-proliferated liquid crystalline phases
Oleh Tovkach, Junbo Chen, Monica M. Ripp +3
Thin solids often develop elastic instabilities and subsequently complex, multiscale deformation patterns. Revealing the organizing principles of this spatial complexity has ramifi…
Hexadecapolar colloids
Bohdan Senyuk, Owen Puls, Oleh M. Tovkach +2
Outermost occupied electron shells of chemical elements can have symmetries resembling that of monopoles, dipoles, quadrupoles and octupoles corresponding to filled s-, p-, d- and…
Electro-osmosis in nematic liquid crystals
O. M. Tovkach, M. Carme Calderer, Dmitry Golovaty +2
We derive a mathematical model of a nematic electrolyte based on a variational formulation of nematodynamics. Extending our previous work, we consider a general setup which incorpo…
Surface induced structures in nematic liquid crystal colloids
S. B. Chernyshuk, O. M. Tovkach, B. I. Lev
We predict theoretically the existence of a class of colloidal structures in nematic liquid crystal (NLC) cells, which are induced by surface patterns on the plates of the cell (li…
Elastic octopoles and colloidal structures in nematic liquid crystals
S. B. Chernyshuk, O. M. Tovkach, B. I. Lev
We propose a simple theoretical model which explains a formation of dipolar 2D and 3D colloidal structures in nematic liquid crystal. Colloidal particles are treated as effective h…
