phy031 Atomic and Molecular Physics (Vollständige Modulbeschreibung)

Präsenzzeit 84h, Selbststudium: 96h

phy509 Mechanics & phy540 Mathematical Methods for Physics and Engineering I

Students gain knowledge of the basic principles of atomic and molecular physics. They gain the ability to distinguish between classical and quantum mechanical descriptions of microscopic matter by discussing key experiments. They acquire the competence to combine knowledge from experimental physics with mathematical and theoretical skills to interpret and qualitatively or quantitatively describe phenomena of atomic and molecular physics. The exercises and tutorials deepen the knowledge by assigning appropriate homework.

Concepts of atomic models; angular momentum, spin, and magnetic properties of the hydrogen atom; interaction with electric and magnetic fields; wave-particle dualism; introduction to quantum mechanics: photons, wave packets, Schrodinger equation, Heisenberg uncertainty principle relativity and Dirac equation; coupling schemes and atomic spectra; absorption and emission, transition probabilities; spectroscopic methods; bosons and fermions, periodic system of the elements; introduction to molecular physics; molecular spectra, rotational and vibrational excitation; selection rules.

Applications: the electron in the box, the harmonic oscillator, the hydrogen atom, fine and hyperfine structure, line shapes, spectroscopy and modern experimental methods
