Quantum Mechanics

This text builds a solid introduction to the concepts and techniques of quantum mechanics in settings where the phenomena treated are sufficiently simple that the student does not face two fundamental difficulties simultaneously: that of learning quantum mechanics and that of learning how to assess the validity of models or the reliability of approximations. The treatment thus confines itself to systems that can either be solved exactly or be handled by well-controlled, plausible approximations. With few exceptions, this means systems with a small number of degrees of freedom. The exceptions are a first pass at many-electron atoms, the electromagnetic field, and the Dirac equation. (The inclusion of these last two topics reflects the now widely held belief that every physicist should have at least a nodding acquaintance with these cornerstones of modern physics.Gottfried, Kurt is the author of 'Quantum Mechanics', published 1968 under ISBN 9780465099993 and ISBN 0465099998.
