Physics 3 is a course package in modern physics. Its aim is to cover a broad spectrum of what is the most important parts of this field in general, and in Lund in particular. The package consists of four courses:
Atomic and Molecular Physics
Angular momenta, hydrogen atom, fine structure, helium atom, LS-approximation in atoms with two valence electrons, centralfield approximation. Radiative transitions, X-ray spectra. Interaction with external field, hyperfine and isotope effects. Cold atoms. Distribution laws, radiative transport. Two-atomic molecules, applications in laser- and astrophysics.
Masses and binding energies of atomic nuclei, macroscopic views and models, decay modes (fission, alpha, beta, gamma) in view of strong, weak and electromagnetic interactions, applied nuclear physics in research an society, systems of two nucleons and microscopic models (shell model), nuclear reactions, cross sections and reaction mechanisms, nuclear structure, fusion, nuclear astrophysics.
Solid State Physics
Chemical bonding in solids, Lattice structure, Diffraction phenomena; the reciprocal lattice, Lattice vibrations; thermal properties and heat transport by phonons, Free electron model; electronic energy bands, Transport phenomena, Semiconductor physics, Magnetism and Superconductivity.
Leptons, quarks, and hadrons. Forces and particles. Strong, weak and electromagnetic interactions. "The Standard Model" of interactions between quarks and leptons. The Higgs mechanism. The common structure of the fundamental forces. The expansion and evolution of the Universe. Critical density and dark matter. Nucleosynthesis in Big Bang and stars. Stellar evolution, neutronstars and black holes.
