Quantum Mechanics

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 covers the material which is traditionally presented in textbooks, but also is especially suitable for introducing the spin, i.e., the most important quantum observable. This emphasis on spin paves the way for 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)

Daniel R. Bes made his undergraduate studies at the University of Buenos Aires, UBA, (1950-54), and performed the equivalent of graduate work at the Niels Bohr Institute, NBI, (1956-59), under the advice of A. Bohr and B. Mottelson (Nobel prizes, 1975), on the subject of vibrations in deformed nuclei. Later on Bes became a frequent visitor to the NBI.

Since 1962 he was part in the construction of a first rate Department of Physics at UBA, an experience drastically interrupted in 1966 for political reasons. Subsequently Bes held positions at Carnegie-Mellon University (1967-68) and at the University of Minnesota (1968-71), where he became Full Professor. In 1971 he returned to Argentina, to work at the Comisión Nacional de Energía Atómica, through an appointment from the Consejo Nacional de Investigaciones Científicas y Técnicas (an arrangement from which he presently benefits again). Between 1998-2003 he was Dean of the newly created Facultad de Ingeniería of the Universidad Favaloro. He has been cofounder of the magazine Ciencia Hoy (1989), and President of the Asociación Física Argentina (1994-1998).

Bes has been author/coauthor of more than 120 publications in international physics journals. He has also been interested on topics such as nuclear disarmament and the Latinoamerican debt.
