Liquid crystals, polymers and polymer liquid crystals are soft
condensed matter systems of major technological and scientific
interest. An understanding of the macroscopic properties of these
complex systems and of their many and interesting peculiarities at
the molecular level can nowadays only be attained using computer
simulations and statistical mechanical theories. Both in the Liquid
Crystal and Polymer fields a considerable amount of simulation work
has been done in the last few years with various classes of models
at different special resolutions, ranging from atomistic to
molecular and coarse-grained lattice models. Each of the two fields
has developed its own set of tools and specialized procedures and
the book aims to provide a state of the art review of the computer
simulation studies of polymers and liquid crystals. This is of
great importance in view of a potential cross-fertilization between
these connected areas which is particularly apparent for a number
of experimental systems like, e.g. polymer liquid crystals and
anisotropic gels where the different fields necessarily merge. An
effort has been made to assess the possibilities of a coherent
description of the themes that have developed independently, and to
compare and extend the theoretical and computational techniques put
forward in the different areas.
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.
Computer simulations provide an essential set of tools for
understanding the macroscopic properties of liquid crystals and of
their phase transitions in terms of molecular models. While
simulations of liquid crystals are based on the same general Monte
Carlo and molecular dynamics techniques as are used for other
fluids, they present a number of specific problems and
peculiarities connected to the intrinsic properties of these
mesophases. The field of computer simulations of anisotropic fluids
is interdisciplinary and is evolving very rapidly. The present
volume covers a variety of techniques and model systems, from
lattices to hard particle and Gay-Berne to atomistic, for
thermotropics, lyotropics, and some biologically interesting liquid
crystals. Contributions are written by an excellent panel of
international lecturers and provides a timely account of the
techniques and problems in the field.
