Triply periodic smectic liquid crystals.
Twist-grain-boundary phases in smectics are the geometrical analogs of the Abrikosov flux lattice in superconductors. At large twist angles, the nonlinear elasticity is important in evaluating their energetics. We analytically construct the height function of a pi2 twist-grain-boundary phase in smectic-A liquid crystals, known as Schnerk's first surface. This construction, utilizing elliptic fu...
متن کاملSmectic phases in ionic liquid crystals
Ionic liquid crystals (ILCs) are anisotropic mesogenic molecules which carry charges and therefore combine properties of liquid crystals, e.g. the formation of mesophases, and of ionic liquids, such as low melting temperatures and tiny triple-point pressures. Previous density functional calculations have revealed that the phase behavior of ILCs is strongly affected by their molecular properties...
متن کاملThermally Stimulated Depolarization Currents in NaCl:Ca Crystals
Analysis of the thermally stimulated depolarization currents in Ca-doped NaCl crystals is carried out by taking into account the presence of the Ca-cation vacancy complexes with vacancies in both nearest-neighbourhood and next-nearest neighbourhood position. Relaxation parameters are derived by fitting the experimental data to standard equations. The results are, where possible, compared with t...

متن کاملSmectic layer instabilities in liquid crystals.
Scientists aspire to understand the underlying physics behind the formation of instabilities in soft matter and how to manipulate them for diverse investigations, while engineers aim to design materials that inhibit or impede the nucleation and growth of these instabilities in critical applications. The present paper reviews the field-induced rotational instabilities which may occur in chiral s...
