Beschreibung
By systematically covering both the Heisenberg and Schrödinger realizations, the book emphasizes the essential principles of quantum mechanics, which remain hidden within the usual derivations of the wave equation. Moreover, this presentation not only to covers the material which is traditionally presented in textbooks, but is also especially suitable for introducing the spin, i.e., the most important quantum observable. This emphasis on spin paves the way to a presentation of recent quantum-mechanical concepts such as entanglement and decoherence, and to recent applications including cryptography, teleportation and quantum computation.

"I am very impressed with Dr. Bes' approach to the subject, the clarity of his exposition, and the timeliness of the examples, many of which are taken from the most recent developments of the "old-new" field of quantum mechanics" (Prof. J. Roederer)
Excellent didactic introduction to the essential principles Treats recent concepts such as entanglement and decoherence Gives background needed to understand quantum cryptography, teleportation and computation Especially suitable for introducing the spin Comment by Prof. J.

Starting from basic principles, the book systematically covers both Heisenberg and Schrödinger realizations of quantum mechanics (in this order). Additions and changes found in the second edition include a more friendly presentation to Hilbert spaces, more practical applications e.g. scanning tunneling microscope (potential barrier), quantum dots (single-particle states in semiconductors), and lasers and masers (induced emission). There are examples of real experiments that have recently provided a qualitative change in the foundations of quantum physics, and the book provides an outline of the density matrix formalism as applied to a simple model of decoherence. There is an excellent didactic introduction to the essential principles, and the book treats recent concepts such as entanglement and decoherence, as well as giving the background needed to understand quantum cryptography, teleportation and computation. The book is especially suitable for introducing the spin.

From the reviews:
"Daniel Bes clearly understands that accuracy, clarity and brevity … . has therefore made a careful selection of the topics to make an accessible concise book on quantum mechanics for a modern introductory undergraduate course. The book has several good features. The claims that this is a modern textbook are well justified by the inclusion of … . the flow of the main ideas is not unbalanced by laborious detail." (Professor J. E. Carroll, Contemporary Physics, Vol. 46 (4), 2005)
"This book accomplishes all the goals implied by its title: it is ‘modern’, ‘concise’ and ‘introductory’. It is concise (just two hundred pages) but covers an extraordinary range of topics, from those typically found in traditional quantum mechanics textbooks … . All this is illustrated with examples that cover a wide range … . This book provides a large amount of information per page and the selection, extension and balance of topics is adequate for an introductory course." (Adán Cabello, Mathematical Reviews, 2005)
"The author has nicely made a systematic dual presentation of both the Heisenberg matrix mechanics and Schödinger wave mechanics … . This wonderful textbook will certainly be a valuable addition to the physics/chemistry library of a science college/university/institute." (Samir Saha, Indian Journal of Physics, Vol. 79 (12), 2005)
"This book is a very clear, comprehensive, concise, and updated introduction to quantum mechanics (QM). … Bes’ book has a great advantage over the other texts: it is updated with some of the most recent advances in quantum theory, including quantum computation and teleportation. The book is supposed to be suitable to undergraduate and first year graduate students. … The problems in the book are few but very stimulating. Besides, there are many figures, graphics, and tables, that really help the reader." (Adonai S. Sant’Anna, Zentralblatt MATH, Vol. 1052,2005)
