A comprehensive and engaging textbook, providing a graduate-level, non-historical, modern introduction of quantum mechanical concepts.Modern Quantum Mechanics is a classic graduate level textbook, covering the main quantum mechanics concepts in a clear, organized, and engaging manner. The original author, J. J. Sakurai, was a renowned theorist in particle theory. The Third Edition, revised by Jim Napolitano, introduces topics that extend the text’s usefulness into the twenty-first century such as advanced mathematical techniques associated with quantum-mechanical calculations, while at the same time retaining classic developments such as neutron interferometer experiments, Feynman path integrals, correlation measurements, and Bell’s inequality.
