Research project Antimatter atoms and ions

We study methods to create and probe atoms and ions made of antimatter, with the purpose to test fundamental symmetries of nature.

In this project I will study how antihydrogen atoms and ions can be used for high-precision tests of fundamental matter-antimatter symmetries.

My work is theoretical, but closely connected to experiments. I am a member


of two international collaborations: ALPHA and GBAR.

This research project has no members.

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.

Particle physics: Antimatter falls just like ordinary matter

Direct observations of antihydrogen atoms free-falling, indicating that antimatter is subject to the same gravitational pull as ordinary matter, are reported in Nature this week. Svante Jonsell is a Researcher and senior lecturer in Atomic Physics at Fysikum.
