Research project Few-body physics

We examin universal properties of certain three-body systems using theoretical and numerical methods.

This project concerns Efimov states in systems of ultracold atoms. We will theoretically investigate the degree of universality in these systems, with special interest to recent unexpected experimental findings. Our tool will be a new code to solve the three-body Faddeev equations in the low-energy limit. They will be designed to work for a wide range of different two-body potentials.

Svante researches antiatoms and antiions

After completing his PhD in Uppsala and later researching at Nordita in Copenhagen and Umeå University, he moved on to the University of Swansea, Wales. Eventually he returned to Sweden and Fysikum. He lives in Uppsala again and has two grown-up daughters who are studying biology and the history of ideas. “Since 2010, I have a lectureship at Fysikum and research on antiatoms and antiions. Many researchers are part of the international ALPHA collaboration, which have published an article in Nature Physics in January 2025.
