The influence of confinement on the spectrum of collective excitations in ultrathin nematic layers of octylcyanobiphenyl is studied, using quasielastic light scattering in planarly and hybridly aligned films. Both systems show confinement-induced rel

The scattering of light by thin nematic liquid crystal films is studied. The distribution of fluctuation wavevectors relevant to the scattering is peaked around the difference between the wavevectors of the scattered and the incident light ray. The w

Light scattering by thin nematic liquid crystal films is considered. The confinement has two important consequences. First, fluctuations with wave vectors not equal to the difference between the wave vectors of the scattered and the incident light ra

Order parameter dynamics near the Lifshitz point in a ferroelectric liquid crystal

Autor: M.M. Wittebrood, Boštjan Žekš, Th. Rasing, Igor Muševič, Robert Blinc

Publikováno v: Physica B: Condensed Matter. 211:331-334

The order parameter dynamics has been measured by photon autocorrelation spectroscopy close to the λ-line of a ferroelectric liquid crystal in a transverse magnetic field. It is shown that the critical dynamics can be observed and analysed in the vi

Dynamics of Protein-Surfactant Exchange at the Air-Water Interface Studied by Optical Second Harmonic Generation and Ellipsometry

Autor: Theo Rasing, M.M. Wittebrood, S.W.H. Eijt, M.A.C. Devillers

Publikováno v: Langmuir. 10:4498-4502

The exchange behavior between proteins and surfactants at the water-air interface has been studied using optical second harmonic generation and ellipsometry. At low surfactant concentrations the proteins force the adsorbed surfactants to dissolve, wh

Gapless Phason in an Antiferroelectric Liquid Crystal

Autor: Theo Rasing, M.M. Wittebrood, Hiroshi Orihara, Igor Muševič, Martin Čopič, Bostjan Zeks, Y. Ishibashi, Robert Blinc

Publikováno v: Physical Review Letters, 71, 1180-1183
Physical Review Letters, 71, 8, pp. 1180-1183

The dynamics of liquid crystals is in certain respects richer than the dynamics of 3D periodic solids. In con trast to these systems, many liquid crystalline phases ex hibit a continuous rotational symmetry, which can be broken at the transition
