Hey I'm Yannik! A young physicist in the making, that also enjoys coding.
I am currently working on my Ph.D. in physics at the Humboldt University in Berlin, where I am working on the string theory aspects of the AdS/CFT correspondence. Already since my childhood I wanted to know how our universe works on its deepest levels, and that curiosity grew only stronger over time. During my studies I further developed a strong interest in the mathematical foundations of physics. The thorough perspective you get on the inner mathematical structures of physical theories is what I enjoy most about this subdiscipline. And further, it helped me getting the sorts of insides into the physical laws that I like the most.
For my thesis project I am part of Stijn van Tongeren's group working on various aspects of integrable models in the context of the AdS/CFT correspondence. I am focusing on the superstring on AdS₅⨉S⁵ and its integrable deformations. My broader goal for the time as a Ph.D. is to explore what the world of research looks like from the inside as much as possible.
I was doing my graduate studies abroad in the Netherlands. Concretely I attended the Theoretical Physics Master's program at the university of Utrecht. For my Master's thesis with Prof. Thomas Grimm I was working on the classification of Calabi-Yau fourfold moduli spaces in the context of the Swampland Distance Conjecture. It's available here.
I did my undergraduate studies in Würzburg, Germany, and wrote my Bachelor's thesis about the unitarity properties of a scattering process in a massive graviton theory. I was supervised by Prof. Thorsten Ohl and you can read it here. I liked the exposure to some of the depths of quantum field theory I got there.
Besides doing analytical calculations with pen and paper, I also enjoy tinkering around with computers and doing coding of all sorts. As a student assistant I created a program for the calculation of the band structure of topological insulators within a k-dot-p model. I did this with the help and under the supervision of M.Sc. Jan Böttcher and Prof. Ewelina Hankiewicz and I liked the insights into modern research that came with it.
In my spare time I used to do coding of short movies and 3D graphics together with some friends as the demogroup rtificial. The videos we produced can be summarized as three minutes of flashing visuals and dope sound, pressed into a 64 kilobyte executable. If you like to watch one, try this. I love the contact with art and design I got through this hobby, although I must admit, I'm not really talented at it and kind of stopped doing it. However, I learned a lot about creativity and also the organization of big projects, so I am very happy to have done this.
