In this paper we review the state of the art in the field of liquid-crystal tunable guided-wave
photonic devices, a unique type of fill-once, molecular-level actuated, optofluidic systems …

Biaxial nematic (N b) liquid crystals are a fascinating condensed matter phase that has
baffled, for more than thirty years, scientists engaged in the challenge of demonstrating its …

We show that surface interactions can vectorially structure the three-dimensional
polarization field of a ferroelectric fluid. The contact between a ferroelectric nematic liquid …

Bent-core mesogens derived from 4-cyanoresorcinol with terminal alkyl chains have been
synthesized and investigated by polarizing microscopy, XRD and electro-optical methods …

We numerically study structural transitions inside shallow sub-micrometre scale wells with
square cross section, filled with nematic liquid crystal material. We model the wells within the …

Using an atomic force microscopy, we have measured the separation dependence of the
force between an atomically flat mica sheet and a micrometer-sized glass sphere immersed …

In highly frustrated calamitic nematic liquid crystals, a strong elastic distortion can be
confined on a few nanometers. The classical elastic theory fails to describe such systems …

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 …

The switching properties of nematic liquid crystals under electrical and mechanical stresses
play a fundamental role in the design and fabrication of electro-optical devices. Depending …

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 …
