Continuing the exceptional tradition of the previous editions, Quantum Mechanics, Fourth Edition provides essential information about atomic and subatomic systems and covers some modern applications of the field. Supported by a Web page that contains a bibliography, color versions of some of the illustrations, and links to other relevant sites, the book shows how cutting-edge research topics of quantum mechanics have been applied to various disciplines. It first demonstrates how to obtain a wave equation whose solutions determine the energy levels of bound systems. The theory is then made more general and applied to a number of physical examples. Later chapters describe the connection between relativity and quantum mechanics, give some examples of how quantum mechanics has been used in information processing, and, finally, discuss the conceptual and philosophical implications of the subject. New to the Fourth Edition: A chapter on quantum information processing that includes applications to the encryption and de-encryption of coded messages A chapter on relativistic quantum mechanics and introductory quantum field theory Updated material on the conceptual foundations of quantum physics containing discussions of non-locality, hidden variables, and parallel universes Expanded information on tunneling microscopy and the Bose-Einstein condensate Presenting up-to-date information on the conceptual and philosophical aspects of quantum mechanics, this revised edition is suitable both for undergraduates studying physics, chemistry, or mathematics and for researchers involved in quantum physics. "This book is the fourth edition of a successful textbook first published over twenty years ago. It covers quantum mechanics for physics undergraduates. It assumes a knowledge of elementary atomic physics and of mathematics typical of that possessed by a student at the end of the first year of a physics degree course, and it includes aspects of the subject required by students on more specialised courses." "New chapters have been added on Relativistic Quantum Theory and Quantum Information; the latter includes discussions of quantum cryptography, quantum teleportation and quantum computing - all of which have been front-line research topics during the last few years. The first edition was unusual for including a chapter on the conceptual and philosophical aspects of the subject. This has been largely rewritten for the present edition so as to present an up-to-date account of work in this fascinating field." -- Book Jacket Quantum mechanics was developed as a response to the inability of the classical theories of mechanics and electromagnetism to provide a satisfactory explanation of some of the properties of electromagnetic radiation and of atomic structure.
