How to make a “movie”…
How to make a “movie” using laser pulses // Hi, I’m Julian and I’m currently a PhD student in the research group of Prof. Paul van Loosdrecht at the University of Cologne in the II. Institute of Physics. I deal with the investigation of ultrafast processes in solids,...
Experiment and Theory
Experiment and Theory working together to find a donut // Hey, my name is Thomas and right now I am a PhD student in the group of Prof. Achim Rosch at the University of Cologne. When I did my bachelor studies, I thought that experimental physics and theoretical...
Lasers and Coffee
Lasers and Coffee – the Optical Condensed Matter Science group at work // That's what experimentalists do when they're not in the lab: have a coffee and play around with laser guns! The coffee machine was one of the first items Paul has ordered when he started the...
Reving up for the next funding period
Project Leaders' Meeting September 2023 // Next summer, we are hoping to prolong our CRC for another four years. We look back on three very active and productive years during the second funding period. Despite all the obstacles related to the pandemic, we have managed...
Our PhDs about their research:
Nina del Ser and Anne Matthies on Archimedes‘ Screws
In this episode Nina and Anne illustrate how the world‘s smallest screws come about in special types of magnets and how they can be driven.
Marco Magnaterra on Resonant Inelastic Xray Scattering (RIXS)
Ella Nikodem and Jakob Schluck on Quantum Transport in Nanodevices
Transistors and microchips surround us all day. They are made by lithography techniques. Learn how Ella and Jakob use the same technology to create nano-sized devices from a particular class of topological materials to get insights into their quantum nature.
Anjana Uday and Gertjan Lippertz on Quantum Anomalous Hall Effect
How can we make nanometer-thin films of a material with extremely high crystal quality? What is special about a Topological Insulator and how can we even make it magnetic? Follow Anjana and Gertjan to learn how they did it and how this leads to the very intriguing „Quantum Anomalous Hall Effect“.
Florian Lange on the greenhouse effect and non-equilibrium physics
Florian illustrates how the greenhouse effect occurs in a quantum system when driven, e.g. by a laser.
Carsten Bauer on high-temperature superconductivity
In this video Carsten dives into the fascinating phenomenon of superconductivity which would be extremely interesting to realize
at higher temperatures. He shows results from computer simulations into this direction.
Tim Eschmann on spin liquids
What are spins in a magnet and how can they become a liquid? And why can we learn more about this weird liquid by throwing dices many times?
Oliver Breunig on charge puddle
Why do electrons in Topological Insulators come together and form charged blobs? Oliver explains what charge puddles are, how they are made and what the consequences for crystals of Topological Insulators are.
