The course discusses the quantisation of relativistic fields towards formulating Quantum Electrodynamics. It introduces the notion of scalar, spinor and vector fields and it describes their elementary interactions in terms of correlation functions and scattering amplitudes including radiative corrections.

Introduction to Electrodynamics. Discussion and formulation of Maxwell’s equations in vacuum and with matter. Connection to the special theory of relativity.

Introduction to the theory of general relativity. The course puts a strong focus on the mathematical foundations of the theory as well as the underlying physical principles and concepts. It covers selected applications, such as the Schwarzschild solution and gravitational waves.

Mechanics of Elastic Media and Hydrodynamics: Strain and stress tensor, field equations, equilibrium, waves and oscillations. Dynamics of fluids, Euler and Navier-Stokes equations, Bernoulli equation, vortices, waves, potential flows; viscous fluids, Reynolds number, Stokes drag, boundary layers, instabilities.

A guided self-study of original papers and of advanced textbooks in theoretical physics. Within the general topic, determined each semester, participants give a presentation on a particular theme.

General structure of quantum theory: Hilbert spaces, states and observables, equations of motion, Heisenberg uncertainty relation, symmetries, angular momentum addition, EPR paradox, Schrödinger and Heisenberg picture.Applications: simple potentials in wave mechanics, scattering and resonance, harmonic oscillator, hydrogen atom, and perturbation theory.

The lecture covers the concepts of classical and quantum statistical physics. The discussion ranges from foundations to specific systems, including their formalisms and techniques, such as bosonic and fermionic gases, and magnetism. Phenomena, most notably phase transitions, are treated by methods such as exact solutions, mean-field approximations, and the renormalization group.

The course gives an introduction to symmetry groups in physics. It explains the relevant mathematical background (finite groups, Lie groups and algebras as well as their representations), and illustrates their important role across modern physics.

The first (longer) part of the course treats phenomenological thermodynamics. This comprises basic notions such as heat and entropy, as well as the laws of thermodynamics. The second (shorter) part of the course is devoted to classical statistical mechanics. It discusses basic notions such as statistical ensembles.
