Defects in Liquid Crystals: Computer Simulations, Theory and Experiments [Hardcover]

Topological defects are the subject of intensive studies in many different branches of physics ranging from cosmology to liquid crystals and from elementary particles to colloids and biological systems. Liquid crystals are fascinating materials which present a great variety of these mathematical objects and can therefore be considered as an extremely useful laboratory for topological defects.
This book is the first attempt to present together complementary approaches to the investigations of topological defects in liquid crystals using theory, experiments and computer simulations.Proceedings of the NATO Advanced Research Workshop on Computer Simulations of Defects in Liquid Crystals Including their Relation to Theory and Experiment, held in Erice, Sicily, Italy, 19-23 September 2000Preface. 1.
