05.04.2021 Hi everyone, it’s time for a newsletter. A few things have happened since my last newsletter, both concerning my work with Johannes Aastrup and concerning other things. In the following I will try to cover it all. Also, I am going to write something about our research from a birds eye perspective: the broad…Read more Newsletter No. 10
In a recent series of papers [1-3], we have discovered a connection between non-perturbative quantum field theory and the (noncommutative) geometry of configuration spaces. In this post, which has also been published on the noncommutative geometry blog, we would like to outline our findings in a non-technical manner intended for readers, who are familiar with…Read more The Metric Nature of Matter
Hi everyone, Johannes and I have just uploaded a new paper to the archive. This is without any doubt the most important paper that we have published in our careers; I feel very strongly about it. It is clear to me that our project has reached a milestone: what was hitherto an ambitious project with…Read more Newsletter No. 9
29.02.2020 Hi everyone Its time for a newsletter. I’ve got some good news — Johannes and I are making strong progress on the “fermion problem” that I described to you in my last letter. We are now in the process of writing down, double-checking and polishing our analysis and thus I am not ready to…Read more Newsletter No. 8
— “Why are you not employed at a university?” — “Why are you financed by crowdfunding and private sponsors instead of research foundations and universities?” These are questions that I am sometimes asked. I work full-time as a researcher in theoretical physics, I publish in some of the best journals worldwide in theoretical and mathematical…Read more WHY CROWDFUNDING?
One of the key principles behind the two fundamental theories, that scientists discovered in the 20th century — the standard model of particle physics and the theory of general relativity — is locality. Local interactions, local degrees of freedom, local field theories. This is what I would like to discuss now. What is locality? Before…Read more LOCALITY AND ITS DISCONTENTS
In the following I would like to discuss this question: when we search for a fundamental theory, what relationship should there be between the quantum and the classical? Or put differently: which one is primary, the classical or the quantum? The operational arrows of quantum vs. classical Let me try to explain these questions by…Read more Quantum or classical: which is primary?
The noble art of gold digging I sometimes think of fundamental research in terms of the noble art of gold digging. When you dig for gold you need two basic skillsets. First of all, you need to be able to find the right place to dig. And secondly there is the digging itself. And those,…Read more YOUNG RESEARCHERS: GO ROGUE
In the following I will discuss what I consider the most fascinating and intriguing development in theoretical high-energy physics in the past some forty years, namely the research field known as noncommutative geometry. The core business of noncommutative geometry, which is pioneered by the french mathematician and field medalist Alain Connes, is is to produce…Read more Noncommutative Geometry and the Standard Model of Particle Physics
In the following I am going to discuss the theory, which I have developed with the mathematician Johannes Aastrup over the past some 15 years. This work is rather technical and involves several different fields in contemporary theoretical physics as well as new conceptual ideas rooted in modern mathematics. In this piece I am going…Read more A final theory from empty space
