Modern quantum mechanics - 2. edición

This book is designed to be used by students taking a course in quantum mechanics or quantum theory. The prerequisites for this text are calculus and modern physics. The text has formal presentation, suitable for junior and senior levels, but is particularly appropriate for graduate level courses. It has been revised in response to changes and new work in the fields of physics. The text is separated into two parts - theory and applications. The instructor has the option of either interspersing the theory sections with the applications, teaching the book in the order presented or leaving out the applications altogether.

This best-selling classic provides a graduate-level, non-historical, modern introduction of quantum mechanical concepts. The author, J. J. Sakurai, was a renowned theorist in particle theory. This revision by Jim Napolitano retains the original material and adds topics that extend the text’s usefulness into the 21st century. The introduction of new material, and modification of existing material, appears in a way that better prepares the student for the next course in quantum field theory. You will still find such classic developments as neutron interferometer experiments, Feynman path integrals, correlation measurements, and Bell’s inequality. The style and treatment of topics is now more consistent across chapters.

The Second Edition has been updated for currency and consistency across all topics and has been checked for the right amount of mathematical rigor.
