The recent groundbreaking discovery of nonzero neutrino masses and
oscillations has put the spotlight on massive neutrinos as one of
the key windows on physics beyond the standard model as well as
into the early universe. This third edition of the invaluable book
Massive Neutrinos in Physics and Astrophysics is an introduction to
the various issues related to the theory and phenomenology of
massive neutrinos for the nonexpert, providing at the same time a
complete and up-to-date discussion on the latest results in the
field for the active researcher. It is designed not merely to be a
guide but also as a self-contained tool for research with all the
necessary techniques and logics included. Specially emphasized are
the various implications of neutrino discoveries for the nature of
new forces. Elementary discussions on topics such as grand
unification, left-right symmetry and supersymmetry are presented.
The most recent cosmological and astrophysical implications of
massive neutrinos are also dealt with.
For graduate students unfamiliar with particle physics, An
Introductory Course of Particle Physics teaches the basic
techniques and fundamental theories related to the subject. It
gives students the competence to work out various properties of
fundamental particles, such as scattering cross-section and
lifetime. The book also gives a lucid summary of the main ideas
involved. In giving students a taste of fundamental interactions
among elementary particles, the author does not assume any prior
knowledge of quantum field theory. He presents a brief introduction
that supplies students with the necessary tools without seriously
getting into the nitty-gritty of quantum field theory, and then
explores advanced topics in detail. The book then discusses group
theory, and in this case the author assumes that students are
familiar with the basic definitions and properties of a group, and
even SU(2) and its representations. With this foundation
established, he goes on to discuss representations of continuous
groups bigger than SU(2) in detail. The material is presented at a
level that M.Sc. and Ph.D. students can understand, with exercises
throughout the text at points at which performing the exercises
would be most beneficial. Anyone teaching a one-semester course
will probably have to choose from the topics covered, because this
text also contains advanced material that might not be covered
within a semester due to lack of time. Thus it provides the
teaching tool with the flexibility to customize the course to suit
your needs.
This book provides a lucid introduction to the basic ideas of
quantum mechanics. Meant for undergraduate and graduate physics
students, it contains discussions on advanced topics that will be
beneficial for researchers also. The text is designed according to
the syllabi followed in major Indian universities. Chapters are
designed to provide an equal emphasis to physical as well as
mathematical significance of concepts. The text is divided in four
parts. The first part introduces concepts of formalism and includes
topics, namely wave-particle duality, state vectors, and symmetry.
The second part comprises discussions on exactly solvable problems.
This is followed by the third part which deals with various
approximation techniques including degenerate and non-degenerate
perturbation theory, WKB approximation, and Born approximation. The
fourth part of this book deals with advanced topics like
permutation symmetry, Dirac particle in a central potential, and
EPR paradox.
An algebraic structure consists of a set of elements, with some
rule of combining them, or some special property of selected
subsets of the entire set. Many algebraic structures, such as
vector space and group, come to everyday use of a modern physicist.
Catering to the needs of graduate students and researchers in the
field of mathematical physics and theoretical physics, this
comprehensive and valuable text discusses the essential concepts of
algebraic structures such as metric space, group, modular numbers,
algebraic integers, field, vector space, Boolean algebra, measure
space and Lebesgue integral. Important topics including finite and
infinite dimensional vector spaces, finite groups and their
representations, unitary groups and their representations and
representations of the Lorentz group, homotopy and homology of
topological spaces are covered extensively. Rich pedagogy includes
various problems interspersed throughout the book for better
understanding of concepts.
