Tunable Cholesteric Liquid Crystal Color

Liang-Chy Chien, Kent State University Abstract: Cholesteric liquid crystals (CLCs) in the planar texture possess the unique feature of separating incident light into its left- and right-handed circular components by reflecting one component and transmitting the other.1,2 In a planar aligned CLC with a preselected helical pitch only a single wavelength can be Bragg reflected (monochrome). In addition to the temperature dependence of Bragg reflected wavelength of a CLC, there are two ways...

Universal Aspects of Liquid Crystals

Pavel Pieranski, University of Paris-Sud Abstract: My intention is to focus on a few selected topics that can be interesting also for non specialists. In particular, I would like to say some words about Mark Kac (one the glorious mathematicians from the Lviv School of Mathematics) and the issue of isospectral drum initiated by him.
