QUANTUM MECHANICSAn innovative approach to quantum mechanics that seamlessly combines textbook and problem-solving book into oneQuantum Mechanics: Concepts and Applications provides an in-depth treatment of this fundamental theory, combining detailed formalism with straightforward practice. Thoroughly integrating close to seven hundred examples, solved problems, and exercises into a well-structured and comprehensive work, this textbook offers instructors a pedagogically sound teaching tool, students a clear, balanced and modern approach to the subject, and researchers a quick practical guide. The extensive list of fully solved examples and problems have been carefully designed to guide and enable users of the book to become proficient practitioners of quantum mechanics.The text begins with a thorough description of the origins of quantum physics before discussing the mathematical tools required in the field and the postulates upon which it is founded. Quantum Mechanics: Concepts and Applications is broad in scope, covering such aspects as one-dimensional and three- dimensional potentials, angular momentum, rotations and addition of angular momenta, identical particles, time-independent and -dependent approximation methods, scattering theory, relativistic quantum mechanics, and classical field theory among others. Each of these diverse areas are enhanced with a rich collection of illustrative examples and fully-solved problems to ensure complete understanding of this complex topic.Readers of the third edition of Quantum Mechanics: Concepts and Applications will also find: Two new chapters - one dealing with relativistic quantum mechanics and the other with the Lagrangian derivations of the Klein-Gordon and Dirac equations - and three new appendices to support them About 90 solved examples integrated throughout the text that are intended to illustrate individual concepts within a broader topic About 200 fully-solved, multi-step problems at the end of each chapter that integrate multiple concepts introduced throughout the chapter More than 400 unsolved exercises that may be used to practice the ideas presented A Solutions Manual is available from the author, Prof. Nouredine Zettili, nzettili@jsu.edu, only to those instructors adopting the book, on request, offering detailed solutions to all exercises.Quantum Mechanics: Concepts and Applications is a comprehensive textbook which is most useful to senior undergraduate and first-year graduate students seeking mastery of the field, as well as to researchers in need of a quick, practical reference for the various techniques necessary for optimal performance in the subject....
