content: | The concepts and methods of effective field theory, along with renormalization and the renormalization group, are of fundamental importance in many modern applications of quantum field theory. The term "effective field theory" means that at sufficiently low energies/long distances (or in some more general limits) essentially any fundamental microscopic theory can be approximated by a local quantum field theory. Relevant cases of such an approximation are solids/condensed matter systems which can be approximated by continuous local field theories, grand unified theories which can be approximated by the Standard Model of particle physics, or the Standard Model of particle physics which can be approximated by QED at low energies. Renormalization and the renormalization group allow to optimize the parametrization of quantum field theories. Important physical effects can often be absorbed in a redefinition of parameters (e.g. so-called running couplings), which allows efficient computations and a deep physical understanding of phenomena. All these points are explained in detail in the lecture. The lecture focuses particularly on working out numerous examples of importance in current research, related e.g. to the Higgs boson, its mass and couplings, to the magnetic moment g-2 of the muon, to hadrons and to grand unification. | |

The subsequent discretization, programming and verification of numerical results constitute the main practical part of this course. The whole "computational thinking" workflow with a particular emphasis on energy-to-solution metrics will be studied in detail on examples from computational fluid dynamics, plasma physics, photonics and quantum electrodynamics. Students are encouraged to develop their computer skills by solving related problems on small to medium high performance computing environments. n energy-to-solution metrics will be studied in detail on examples from computational fluid dynamics, plasma physics, photonics and quantum electrodynamics.
