Applied Quantum Mechanics

Quantum mechanics is the fundamental law governing all of nature, including materials and devices. As devices become smaller, understanding its principles becomes increasingly important for studying their behavior. This book fills a gap in graduate engineering and physics education by providing a systematic presentation of quantum theory's applications. It covers essential concepts and approximations needed to estimate properties of various systems, such as nuclei, atoms, molecules, solids, lasers, and other quantum-optic devices. The topics covered include foundations, simple systems, Hamiltonian mechanics, atoms and nuclei, molecules, crystals, transitions, tunneling, statistical mechanics, transport, noise, energy bands, electron dynamics in solids, vibrations in solids, creation and annihilation operators, phonons, photons and lasers, coherent states, Coulomb effects, cooperative phenomena, magnetism, shake-off excitations, and exercise problems. A supplementary Instructor's Solutions Manual is available for this book.
