For more than 25 years Alastair Raes Quantum Mechanics" has been one of the most highly regarded textbooks in this area. From elementary atomic physics & mathematics to angular momentum & time dependence to relativity & quantum computing the text shows how cutting-edge research topics of quantum mechanics have been applied to various disciplines. Retaining the clarity of its predecessors this fifth edition presents revised & updated material throughout the text. It offers a clear exposition of fundamental ideas additional worked examples of the application of quantum mechanics principles to a range of physical problems & more information on modern quantum information technology. This text was one of the first to include a substantial discussion of the conceptual & philosophical implications of quantum mechanics which has been revised & extended in the fifth edition. Other topics covered include one- & three-dimensional Schrodinger equations angular momentum time-independent perturbation theory time dependence scattering & relativity. Cementing its reputation as an exceptional introductory textbook " Quantum Mechanics Fifth Edition" fully covers the concepts of quantum mechanics taught in an undergraduate physics course & provides the foundation necessary for other specialized courses."
