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…
Toroidal nuclei of columnar lyotropic chromonic liquid crystals coexisting with isotropic phase
Runa Koizumi, Dmitry Golovaty, Ali Alqarni +4
Nuclei of ordered materials emerging from the isotropic state usually show a shape topologically equivalent to a sphere; the well-known examples are crystals and nematic liquid cry…
Ion-dependent DNA Configuration in Bacteriophage Capsids
Pei Liu, Javier Arsuaga, M. Carme Calderer +3
Bacteriophages densely pack their long dsDNA genome inside a protein capsid. The conformation of the viral genome inside the capsid is consistent with a hexagonal liquid crystallin…
A Novel Landau-de Gennes Model with Quartic Elastic Terms
Dmitry Golovaty, Michael Novack, Peter Sternberg
Within the framework of the generalized Landau-de Gennes theory, we identify a -tensor-based energy that reduces to the four-constant Oseen-Frank energy when it is considered ov…
Phase Transitions in Nematics: Textures with Tactoids and Disclinations
Dmitry Golovaty, Young-Ki Kim, Oleg D. Lavrentovich +2
We demonstrate that a first order isotropic-to-nematic phase transition in liquid crystals can be succesfully modeled within the generalized Landau-de Gennes theory by selecting an…
Q-tensor model for electrokinetics in nematic liquid crystals
Oleh M. Tovkach, Christopher Conklin, M. Carme Calderer +4
We use a variational principle to derive a mathematical model for a nematic electrolyte in which the liquid crystalline component is described in terms of a second-rank order tenso…
