Based on graduate lectures given by the authors, Smectic and Columnar Liquid Crystals: Concepts and Physical Properties Illustrated by Experiments examines lamellar (smectic) and columnar liquid crystals, which, in addition to orientational order, possess 1D, 2D or 3D positional order. Topics include rheology and plasticity, ferroelectricity, analogies with superconductors, hexatic order and 2D-melting, equilibrium shapes, facetting, and the Mullins-Sekerka instability, as well as phase transitions in free films and membrane vibrations. Nematic and cholesteric liquid crystals are covered by the authors in a separate volume entitled Nematic and Cholesteric Liquid Crystals: Concepts and Physical Properties Illustrated by Experiments.

Liquid Crystals & Biological Structures covers analogies between biological structures and behavior of living cells to liquid crystalline structures and their behavior. It emphasizes that the physical state of the matter involved in life processes is to a great extent liquid crystalline. The first chapters discuss the physical, chemical, structural, and optical properties of liquid crystals, as well as the structure of the principal molecules associated with life systems. The core chapters cover selected cellular structures exhibiting liquid crystalline behavior to emphasize the nature of various cellular membranes, from the cell membranes to the receptors and effectors. The book also considers differentiated organelles of the cell that are specialized for photoreception, including chloroplasts for photosynthesis, the retinal photoreceptors of the eye, and the rods and cones for visual excitation. This book is suited for students and bioscientists who are interested in the potential of the liquid crystalline state in exploring a variety of biological phenomena.

Smectic and lamellar liquid crystals are three-dimensional layered structures in which each layer behaves as a two-dimensional fluid. Because of their reduced dimensionality they have unique physical properties and challenging theoretical descriptions, and are the subject of much current research.

This book describes the general properties of the most popular liquid crystal (LC) phases nematics (Ns) and smectics (Ss), and in addition, is directed to fill in a niche of the LC field. This book covers topics ranging from the types and classifications of liquid crystals to a detail description of the fundamental properties of nematics and smectics, including continuum theory, non-linearity, behaviour in electric field, surface alignment, phase transitions, defect and textures and provides a useful reference intended for advanced topics of the physics of liquid crystals.

This conference on liquid crystals of one- and two-dimensional order and their applications is the third in a series of European conferences devoted mainly to smectic liquid crystals. Its purpose was to bring together people working on the frontiers of the field of liquid crystals. Ordinary nematic liquid crystals were left out in order to limit the size of the meeting. The number of registered participants still reached 148. The conference shed new light on the classification of smectic mesophases, especially through the interaction of the Halle (GDR) and Hull (England) groups. It saw lively discussions on the famous blue phase of cholesterics. There were illuminating presentations on lyotropic nematic liquid crystals, on reentrant nematics, mesomorphic polymer phases, and related subjects. Much room was given to bilayers, monolayers, and interfaces, mostly to further the use of the concepts and methods of liquid crystal physics in exploring bio membranes. Other topics were device applications of smectic and cholesteric liquid crystals and nematic polymers, both of which hold promise of techno logical breakthroughs, apart from their scientific interest.

A range of theoretical studies regarding the static and dynamic behaviour of smectic liquid crystals will be presented. The thesis is mainly concerned with the smectic A phase as modelled by the continuum theory of Stewart, though a working knowledge of the smectic C phase, modelled using the Leslie-Stewart-Nakagawa continuum theory, proves necessary. In Chapter 3, reductions of Stewart's theory by appeal to certain physically motivated assumptions upon the smectic and the flow pattern to which it is subjected are outlined. The linear stability of each of the resultant systems is then analysed. Chapter 4 presents the derivation of a "lubrication-type" theory based on one of these resultant systems of equations, which is then analysed in general terms before being applied to the problem of flow past a finite obstacle. Chapter 5 presents an investigation of a shear wave incident at a planar boundary between an isotropic elastic solid and a smectic A liquid crystal. The behaviour of the wave upon reflection and refraction at the interface is established, as is the response of the smectic; a comparison with the smectic C case as considered by Gill and Leslie concludes the chapter. Finally, Chapter 6 discusses the static configuration of a smectic A liquid crystalin the presence of an isolated edge dislocation. After constructing the energy density to fourth order, we first recover the results of previous investigations by assuming the director and layer normal always coincide, in addition to examining a perturbation to a known solution. We then relax the constraint director-layer normal equivalence, obtaining exact solutions for the smectic's configuration for a quadratic energy density and deriving equilibrium equations for special cases for the fourth order formulation.
