Quantum Physics F

The experimental background of quantum physics, particles and atomic models, the photon, the photoelectric effect, and the spectrum of hydrogen-like atoms. An overview of special relativity. Spectrum. The correspondence principle. Wave-particle duality, probabilities, wave functions, the Schrödinger equation, wave packets. Expectation values, operators, uncertainty relations. Dirac formalism. One-dimensional systems, stationary states, the infinite square well, the harmonic oscillator, transmission, tunnelling and reflection. Three-dimensional systems, the hydrogen atom and one-electron atoms, angular momentum and central motion, transitions, energy level diagrams, and time-independent perturbation theory. Many-electron atoms, spin, the addition of angular momentum, identical particles, fermions and bosons, the Pauli principle, electron configurations, the Zeeman effect, spin-orbit coupling, the central field approximation, fine structure, the periodic system, optical transitions and X-rays, spectroscopy. Briefly about diatomic molecules: bonding, vibrational and rotational motions, transitions. The importance of quantum physics for engineering applications.
