BEADING OF SMECTIC DISCLINATION LINES

These two phases are characterized by a pseudo-hexagonal order within the layers, but they differ from the Sm Bc phases by the direction of the long molecular axes

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

This is qualitatively analogous to the construction of a 3D-crystal surface equilibrium shape with facets being the individual bricks of lowest energy (Fig. 5a)

In the absence of the flexoelectric coupling between the polarization and the tilt of molecules both the frequency and the dielectric strength of the Gold- stone mode do not

The temperature dependence of the critical stress and strain required to induce mechanically one phase from the other, allows the Landau parameters of the transition to

- Recent works [1, 2] on liquid crystals have shown that the dielectric behaviour in the smectic phases is very different than that in the nematic phase.. In this

liquid structure factor just above the nematic-smectic C transition. As the temperature is lowered, the peaks in the scattering intensity move off the z-axis and
