Conceptual and methodical introduction to theoretical physics by taking the example of classical mechanics. Discussion of Lagrangian and Hamiltonian descriptions as well as symmetries and conserved quantities.

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.

An introduction to two-dimensional conformal field theorywill be given.

String theory is an attempt to quantise gravity and unite it with the other fundamental forces of nature. It is related to numerous interesting topics and questions in quantum field theory. In this course, an introduction to the basics of string theory is provided.

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.

Many-body quantum physics rests on symmetry considerations that lead to two kinds of particles, fermions and bosons. Formal techniques include Hartree-Fock theory and second-quantization techniques, as well as quantum statistics with ensembles. Few- and many-body systems include atoms, molecules, the Fermi sea, elastic chains, radiation and its interaction with matter, and ideal quantum gases.

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.

Theoretical Physics for Mathematicians. The course will mainly cover various aspects of Quantum Mechanics.
