This book is unique because unlike others on the subject that
focus on mathematical arguments, this volume emphasizes the
original field concept, aiming at objectives in modern information
technology. Written primarily for undergraduate students of physics
and engineering, this book serves as a useful reference for
graduate students and researchers too. With concise introductory
arguments for the physics of electromagnetism, this book covers
basic topics including the nature of space-time-dependent
radiations in modern applications.
Phase transitions in which crystalline solids undergo structural
changes present an interesting problem in the interplay between the
crystal structure and the ordering process. This text, intended for
readers with some prior knowledge of condensed-matter physics,
emphasizes the basic physics behind such spontaneous structural
changes in crystals. Starting with the relevant thermodynamic
principles, the book discusses the nature of order variables and
their collective motion in a crystal lattice; in a structural phase
transition a singularity in such a collective mode is responsible
for the lattice instability, as revealed by soft phonons. This
mechanism is analogous to the interplay of a charge-density wave
and a periodically deformed lattice in low-dimensional conductors.
The text also describes experimental methods for modulated crystal
structures and gives examples of structural changes in
representative systems. The book is divided into two parts. The
first, theoretical, part includes such topics as: the Landau theory
of phase transitions; statistics, correlations and the mean-field
approximation; pseudospins and their collective modes; soft lattice
modes and pseudospin condensates; lattice imperfections and their
role in the phase transitions of real crystals. The second part
discusses experimental studies of modulated crystals using x-ray
diffraction, neutron inelastic scattering, light scattering,
dielectric measurements, and magnetic resonance spectroscopy.

Nonlinear physics is a well-established discipline in physics
today, and this book offers a comprehensive account of the basic
soliton theory and its applications.
Nonlinear physics is a well-established discipline in physics
today, and this book offers a comprehensive account of the basic
soliton theory and its applications. Although primarily
mathematical, the theory for nonlinear phenomena in practical
environments needs to be understood at upper undergraduate level,
with particular attention given to the presence of media where
nonlinearity takes place. This book addresses mathematical
theories, but also suggests possible theoretical innovations for
many issues, providing a stimulating reference for both students
and researchers.
"This book explores modern thermodynamics of crystalline states,
through the lens of soliton theory. Right from the start, the book
revises traditional theories of these concepts with soliton theory
in mind. Although well-established as a mathematical nonlinear
physics, this is the first time that a book uses soliton theory to
deal with nonlinear processes in crystals, clarifying dynamical
aspects logically, as demonstrated for superconductivity in
modulated crystals. The book explores the soliton theory of
crystalline processes, from irreversible processes in Crystals, to
Phase Transitions and Mesoscopic Disorder, Statistical
Thermodynamics of Modulated Lattices, and Superconductivity"--
