Small-angle neutron scattering (SANS) is one of the most important techniques for
microstructure determination, being utilized in a wide range of scientific disciplines, such as …

The blue phases of cholesteric liquid crystals are liquids that exhibit orientational order
characterized by crystallographic space-group symmetries. We present here a pedagogical …

Liquid Crystal Devices are crucial and ubiquitous components of an ever-increasing number
of technologies. They are used in everything from cellular phones, eBook readers, GPS …

We present a theory of the cholesteric blue phase, assuming a first-order cholesteric-
isotropic transition. We show, on the basis of the Oseen-Frank elasticity equations, that the …

Amorphous solids fall into any reasonable definition of a solid. This means that it should be
possible to describe amorphous solids in terms of an expansion in deviations from a well …

Liquid crystals are partially ordered systems without a rigid, long-range structure. The study
of these materials covers a wide area: chemical structure, physical properties and technical …

Very general symmetry considerations uniquely favor a bcc crystal structure near the melting
line. This agrees with observations that almost all metals on the left-hand side of the periodic …

Mesogenic materials exhibit a multitude of transitions involving new phases. Studies of
these phases are of importance in a wide range of scientific fields and as such have …

Two centuries of research on phase transitions have repeatedly highlighted the importance
of critical fluctuations that abound in the vicinity of a critical point. They are at the origin of …

A review is presented of the theory of optical properties of cholesteric liquid crystals (CLC).
The diffraction nature of the unusual optical properties of CLC is exhibited in the simplest …
