# WP6 Condensed Matter Field Theory (TA4)

Fundamental concepts include: functional integration, perturbation theory, symmetry breaking and collective phenomena, mean-field theory, Bose-Einstein condensation, superfluidity, superconductivity, field theory of interacting electron gas, response functions, renormalization group with applications (e.g. Ising model, dissipative quantum tunnelling, general RG theory, ferromagnetic transition, Kosterlitz-Thouless transition), topological field theory. Theoretical condensed matter physics draws heavily and increasingly on the language of quantum field theory. This course emphasizes the development of modern methods of classical and quantum field theory with applications of interest in both experimental and theoretical condensed matter physics. The main goal is to acquire, via concrete examples, a detailed working knowledge of the application of quantum field theoretical methods to condensed matter systems at a level allowing direct access to present-day research.
