Quantum Mechanics: A Modern Introduction differs from ordinary textbooks on the subject in two important ways: first, it introduces quantized systems and emphasizes quantum principles from the start rather than beginning with an analogy to classical laws or a historical approach; second, it contains a large number of practical examples that illustrate the concepts introduced and allow students to apply what they have learned.

Lectures on Quantum Mechanics

Mathematics

Hindustan Book Agency

These lecture notes have evolved from courses on electromagnetism taught to graduate and undergraduate students by Professor Ashok Das at the University of Rochester. The basics of the subject are explained with clarity and attention to detail that are characteristics of all of his books. The chapters cover, in considerable detail and in logical sequence, topics ranging from electrostatics, magnetostatics and Maxwell's equations to plasmas and radiation. Boundary value problems are treated extensively, as are wave guides, electromagnetic interactions and fields. This second edition has expanded discussions on many topics and a lot more details on the derivation of various equations, particularly in the second half of the book which deals with more advanced topics. All in all, this set of lecture notes, written in a simple and lucid style will complement other texts on electromagnetism and will be a valuable addition to the physics bookshelf.

Lectures on Quantum Field Theory (Second Edition)

"This book comprises the lectures of a two-semester course on quantum field theory, presented in a quite informal and personal manner. The course starts with relativistic one-particle systems, and develops the basics of quantum field theory with an analysis on the representations of the Poincaré group. Canonical quantization is carried out for scalar, fermion, Abelian and non-Abelian gauge theories. Covariant quantization of gauge theories is also carried out with a detailed description of the BRST symmetry. The Higgs phenomenon and the standard model of electroweak interactions are also developed systematically. Regularization and (BPHZ) renormalization of field theories as well as gauge theories are discussed in detail, leading to a derivation of the renormalization group equation. In addition, two chapters - one on the Dirac quantization of constrained systems and another on discrete symmetries - are included for completeness, although these are not covered in the two-semester course. This second edition includes two new chapters, one on Nielsen identities and the other on basics of global supersymmetry. It also includes two appendices, one on fermions in arbitrary dimensions and the other on gauge invariant potentials and the Fock-Schwinger gauge"--

This book consists of the lectures for a two-semester course on quantum field theory, and as such is presented in a quite informal and personal manner. The course starts with relativistic one-particle systems, and develops the basics of quantum field theory with an analysis of the representations of the PoincarÃ© group. Canonical quantization is carried out for scalar, fermion, Abelian and non-Abelian gauge theories. Covariant quantization of gauge theories is also carried out with a detailed description of the BRST symmetry. The Higgs phenomenon and the standard model of electroweak interactions are also developed systematically.

LIE GROUPS AND LIE ALGEBRAS FOR PHYSICISTS

The book is intended for graduate students of theoretical physics (with a background in quantum mechanics) as well as researchers interested in applications of Lie group theory and Lie algebras in physics. The emphasis is on the inter-relations of representation theories of Lie groups and the corresponding Lie algebras.
