## Contents & literature

### Symmetries and conservation laws

Topic for winter semester 2020/2021Symmetries and the conservation laws connected to them play an important role in nearly all areas of physics. In the first talks, the concept of symmetry will first be examined conceptually and in terms of philosophy of science, also using some prominent examples. Later on, the description of symmetries through group theory, symmetries in quantum mechanics and elementary particle physics (e. g. the flavor symmetry SU(3) and gauge symmetries), symmetry breaking as well as scale symmetry will be among the topics.

Topics are primarily given out to master’s students. A limited number of topics can possibly also be worked on by bachelor’s students. Thus, we refer to the seminar on the theory of atoms, nuclei and condensed matter at this point, which is targeted exclusively towards bachelor’s students.
