Local order and orientational correlations in liquid and crystalline phases of carbon tetrabromide from neutron powder diffraction measurements [PDF]
, 2010 The liquid, plastic crystalline and ordered crystalline phases of CBr$_4$ were studied using neutron powder diffraction. The measured total scattering differential cross-sections were modelled by Reverse Monte Carlo simulation techniques (RMC++ and ...

Photoaligning and Photopatterning: New LC Technology
Crystals, 2020 We demonstrate a physical model of photoalignment and photopatterning based on rotational diffusion in solid azo-dye nanolayers. We also highlight the new applications of photoalignment and photopatterning in display and photonics such as: (i) liquid ...

Poincaré-sphere representation of phase-mostly twisted nematic liquid crystal spatial light modulators [PDF]
, 2009 We establish necessary conditions in order to design a phase-only wave front modulation system from a liquid crystal display. These conditions determine the dependence of the polarization state of the light emerging from the display on the addressing ...

Observation of accelerating parabolic beams [PDF]
, 2008 We report the first observation of accelerating parabolic beams. These accelerating parabolic beams are similar to the Airy beams because they exhibit the unusual ability to remain diffraction-free while having a quadratic transverse shift during ...

Аngular optical characteristics of a standard twist indicator with a phase compensator [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: One of the disadvantages of a liquid crystal display device for information on the twist effect is its relatively narrow viewing angle.

Director dynamics in liquid-crystal physical gels [PDF]
, 2007 Nematic liquid-crystal (LC) elastomers and gels have a rubbery polymer network coupled to the nematic director. While LC elastomers show a single, non-hydrodynamic relaxation mode, dynamic light-scattering studies of self-assembled liquid-crystal gels ...
