The asymmetric relaxation of facets together with an estimate of the energy barrier to nucleating new smectic layers suggest that the facet size is blocked very close to rc, Which

Gennes [1] to calculate the critical behaviour of the elastic constants : i) The fluctuations of the smectic order parameter are coupled to the director by means.

- the surface singularity lines running along the stripes leave faint tracks on the glass plate when passing back to the nematic phase. These tracks indicate a

We see that in compounds of the same length the tendency to form a smectic phase is greater in the case of a less symmetric shape. This conclusion was

- Using light beating spectroscopy, we analyse the critical angular fluctuations of the molecules above a second order smectic-A to smectic-C transition.. Comparing

2014 Models are proposed for a modulated smectic phase (Ã) and the cubic smectics (D and a nameless phase) that are based on the material properties of the single
