| Topic | Summary (3rd Ed.) | | :--- | :--- | | | Introduces the crisis in classical physics, wave-particle duality, and the early quantum theory. Sets the stage for a rigorous, formal introduction to the subject. | | 2. Bound States | Applies the Schrödinger equation to simple potentials like the particle in a box, the harmonic oscillator, and the hydrogen atom. | | 3. Formal Theory | Discusses the mathematical underpinnings: Hilbert spaces, operators, eigenfunctions, and the postulates of quantum mechanics. | | 4. Angular Momentum | Covers the quantum mechanics of angular momentum, including spin, raising and lowering operators, and the addition of angular momenta. | | 5. Approximation Methods | Introduces essential techniques for solving problems without exact solutions, such as perturbation theory (time-independent and dependent) and the variational method. | | 6. Scattering Theory | Develops the theory of particle scattering, covering partial wave analysis and the Born approximation. | | 7. Relativistic QM | Concludes with a brief look into relativistic quantum mechanics, including the Klein-Gordon and Dirac equations, bridging the gap to quantum field theory. | Devanathan is a valuable resource for any student
