Point defects in nematics, also called hedgehogs, are topological entities that have no
equivalent in ordered atomic solids, despite the homonymy. They have been the subject of …

Colloidal particles dispersed in a liquid crystal (LC) lead to distortions of the director field.
The distortions are responsible for long-range effective colloidal interactions whose …

Using computer simulations we investigate the microscopic structure of the singular director
field within a nematic droplet. As a theoretical model for nematic liquid crystals we take hard …

Abstract Within the Landau–de Gennes theory of liquid crystals, we study the equilibrium
configurations of a nematic cell with twist boundary conditions. Under the assumption that …

We use the method of Γ Γ-convergence to study the behavior of the Landau-de Gennes
model for a nematic liquid crystalline film in the limit of vanishing thickness. In this asymptotic …

Within the Landau–de Gennes phenomenological theory, we study the influence of an
applied electric field with average strength E a on the position of a nematic line defect with …

We propose a Landau–de Gennes variational theory fit to simultaneously describe isotropic,
nematic, smectic-A, and smectic-C phases of a liquid crystal. The unified description allows …

A strong electric field is able to induce transient and/or local biaxial states within a nematic
calamitic phase, and the resultant nematic texture can be identified by the Landau–de …

Nematic molecules confined in an asymmetric π cell and subjected to strong electric fields
exhibit textural distortions involving nematic order variations, described by the Landau-de …

Nematic liquid crystals possess three different phases: isotropic, uniaxial, and biaxial. The
ground state of most nematics is either isotropic or uniaxial, depending on the external …
