Supersymmetry is a symmetry which combines bosons and fermions in
the same multiplet of a larger group which unites the
transformations of this symmetry with that of spacetime. Thus every
bosonic particle must have a fermionic partner and vice versa.
Since this is not what is observed, this symmetry with inherent
theoretical advantages must be badly broken. It is hoped that the
envisaged collider experiments at CERN will permit a first
experimental test, which is expected to revive the interest in
supersymmetry considerably.This revised edition of the highly
successful text of 20 years ago provides an introduction to
supersymmetry, and thus begins with a substantial chapter on
spacetime symmetries and spinors. Following this, graded algebras
are introduced, and thereafter the supersymmetric extension of the
spacetime Poincare algebra and its representations. The Wess-Zumino
model, superfields, supersymmetric Lagrangians, and supersymmetric
gauge theories are treated in detail in subsequent chapters.
Finally the breaking of supersymmetry is addressed meticulously.
All calculations are presented in detail so that the reader can
follow every step.
Statistics links microscopic and macroscopic phenomena, and
requires for this reason a large number of microscopic elements
like atoms. The results are values of maximum probability or of
averaging. This introduction to statistical physics concentrates on
the basic principles, and attempts to explain these in simple terms
supplemented by numerous examples. The basic principles
concentrated on are the difference between classical and quantum
statistics, the a priori probabilities as related to degeneracies,
the vital aspect of indistinguishability as compared with
distinguishability in classical physics, the differences between
conserved and nonconserved elements (the latter including photons
and phonons), the different ways of counting arrangements in the
three statistics (Maxwell-Boltzmann, Fermi-Dirac, Bose-Einstein),
the difference between maximization of the number of arrangements
of elements in these and averaging in the Darwin-Fowler method.
Significant applications to solids, radiation and to electrons in
metals are treated in separate chapters. Finally the Bose-Einstein
distribution is rederived under condensation conditions. Each
chapter concludes with examples and exercises.
This is a comprehensive text on electrodynamics with detailed
explanations and calculations. One hundred worked examples have
been incorporated, making this book also suitable for
self-instruction. Apart from all traditional topics of the
Maxwell's theory, this book includes the special theory of
relativity and the Lagrangian formalism and applications; the text
also contains introductions to quantum effects related to
electrodynamics, such as the Aharonov-Bohm and the Casimir effects.
Numerous modern applications in diverse directions are treated in
the examples.

in metals are treated in separate chapters, as well as
Bose-Einstein condensation. In this latest edition, apart from a
general revision, the topic of thermal radiation has been expanded
with a new section on black bodies and an additional chapter on
black holes. Other additions are more examples with applications of
statistical mechanics in solid state physics and superconductivity.
Throughout the presentation, the introduction carries almost all
details for calculations.

additional chapter on the Boltzmann transport equation along with
appropriate applications. Also, more examples have been added
throughout, as well as further references to literature.
Electrodynamics is a basic area of physics, encompassing also
classical and quantum physics, optics, relativity and field theory,
and is of universal practical importance. The present text aims at
a balance between basic theory and practical applications, and
includes introductions to specific quantum mechanical effects. The
detailed presentation allows the reader to follow every step. Each
chapter is supplemented by both worked examples and unsolved
exercises. This thoroughly revised second edition with new sections
on networks and diffraction, and with international units stated
wherever relevant, covers all the material normally required for a
first degree in physics and beyond, and may serve as a step to
advanced applications and research.
