Ebook: Quantum Mechanics

The developer of path integrals, Nobel Prize–winning physicist Richard Feynman, presents unique insights into this method and its applications. Feynman starts with an intuitive view of fundamental quantum mechanics, gradually introducing path integrals. Later chapters explore more advanced topics, including the perturbation method, quantum electrodynamics, and statistical mechanics. 1965 edition, emended in 2005 An introduction to the Schrodinger equation --The motion of wave packets -- Schrodinger equation as eigenvalue-eigenfunction equation -- The solution of the Schrodinger equation in one dimension -- Looking through the Heisenberg-Bohr microscope -- The Dirac description of quantum mechanical states -- The one-dimensional harmonic oscillator -- Equations of motion and classical correspondence -- Systems of two degrees of freedom -- Quantum paradoxes and the Copenhagen interpretation -- Angular momentum -- Motion in central potential -- The hydrogen atom -- Electrons in the electromagnetic field -- Spin and matrices -- Matrix mechanics: two-state systems -- The addition of angular momenta -- Approximation methods for stationary states -- Quantum systems: atoms with one and two electrons -- Quantum systems: atoms and molecules -- Quantum systems: Fermi and Bose gases -- Time-dependent perturbation theory and application to atomic radiation and scattering -- Scattering theory -- The unfinished chapter: the meaning and interpretation of quantum mechanics -- Appendix: The delta function
