Electrically driven three-dimensional solitary waves as director bullets in nematic liquid crystals
Nature Communications, 2018 Solitary waves which maintain their shape have many fascinating physical and mathematical properties. Here the authors observe waves trapped along three spatial dimensions in nematic liquid crystals due to an electric field and show that these director ...

Realization of a four-electrode liquid crystal device with full in-plane director rotation [PDF]
, 2007 A liquid crystal device with micrometer-scale hexagonal electrodes has been fabricated and characterized. By using weak anchoring at the liquid crystal interfaces, the orientation of the director is completely governed by the applied electric fields. The

The Freedericksz Transition in a Spatially Varying Magnetic Field
Crystals, 2021 Much is known about the Freedericksz transition induced by uniform electric and magnetic fields in nematic liquid crystals. In this work, we are interested in the effects of a spatially varying field on the transition. Specifically, we study the director
