Photonics I - The theory of light and its advanced applications, part I

Topics: Ray optics; wave optics and Gaussian beams, ABCD matrices and resonators, interferometers; birefringence, nonlinear optics; Fourier optics; Einstein coefficient, rate equations, basics of spectroscopy; attosecond physics, non-perturbative effects.


This course will give an overview of various topics related to laser spectroscopy of atoms and ions. 

The lecture will start from a theoretical description of light-atom interaction using quantum mechanics.

The lecture will also cover experimental methods for laser spectroscopy, which includes Doppler-free spectroscopy, atom/ion-trapping, optical frequency combs and ultra-stable lasers.

We will introduce a few important applications of atomic spectroscopy such as optical clocks and verification of quantum theory by high-precision spectroscopy.


The seminar course covers the physics of biological membranes: membrane elasticity, molecular dynamics of lipids, thermodynamics of lipid mixtures and electrostatics of membranes. The seminar will provide insights into the physics of self-assembly und molecular transport processes. Seminar topics will lead us into lipid-nanoscience and molecular mechanisms that govern the formation and efficiency of mRNA lipid nanoparticles, the indispensable nucleic acid delivery vehicles in mRNA based therapies and vaccination. The course will start with four introductory lectures followed by seminar talks presented by the participants. Students should be part of the physics masters programm. Basic knowledge in undergraduate physics, in particular statistical physics is required.

The surface is the link between a body - a bubble, a piece of metal, a droplet - and the environment. As such, the surface is the place where many physical and chemical phenomena take place. These processes can be highly dependent on the interface under study: solid-liquid, liquid-gas, gas-solid, etc. One remarkable case is the dispersion of a solid in a liquid media, known as colloids. This particular example has impacted strongly in the development of areas such as nanoscience and nanotechnology.

This course provides a basic overview of surfaces, interfaces and colloidal systems. As such, it will merge physics concepts that strongly impact other disciplines such as chemistry, biology and materials science, among others. In this course we will cover the basic concepts, theories, experimental techniques and applications needed to understand different types of interfaces, surfaces and colloidal materials.
