Figure

Figure 3 quantitatively details the low-frequency optical response of the isotropic phase [22].
Figure 4. Low-frequency birefringence is larger for the small molecular weight LC under the same  stress conditions (ω = 0.5 Hz, 250 µm, γ 0  = 10%), +1 °C above the isotropic transition
Figure 5. Optical response (transmittance intensity) measured upon applying a low-frequency  mechanical strain in the isotropic phase of 4-octyl-4′-cyanobiphenyl (8CB) (T − T NI  = +0.1 °C, quartz  substrate, strain rate γ 0  = 100%)
Figure 7. The Rouse model has been explicitly developed in the frame of non-interacting polymer  chains in dilute solutions

We examine the corrections to the liquid crystal mean field theory by generating terms in the liquid crystal free energy density upon integration of the polymer fields. First,

To integrate the dynamic glass transition into the description of the macroscopic dynamics of polymers and liquid crystalline sidechain polymers, it has turned out to be crucial

We compare the macroscopic properties of the CM phase with those of the classical fluid smectic phases, namely smectic A, which is uniaxial, and the classical smectic C phase, that

We first characterize the single-phase flow, in terms of threshold for transition to turbulence, scaling of the torque and measurements of the mean flow and of the Reynolds stress

depends on what kind of fluctuations are present in the smectic A phase : layer undulations or molecular tilt. They could of course, in general, occur

Presumably the acoustical attenuation arises from coupling of sound waves with both fluctuations of the director and magnitude of the order parameter. Unfortunately it is

Precise measurements of the Kerr effect [6, 9] and magnetic birefringence [6, 7] in the isotropic phase of. some nematic substances have been

2014 Nous étudions le diagramme de phase d’un système dense de particules allongées avec une interaction Coulombienne, et montrons l’existence d’une transition
