About me
Professor in theoretical Atomic Physics. I joined Stockholm University in 2009. Before that I was a senior lecturere at Swansea University, Wales.
I am currently subject representative for the postgraduate educations in Physics and I coordinate the courses "Internship in Physics" 7.5/15 ECTS.
The main focus of my research is collision theory connected to the antihydrogen experiments ALPHA and GBAR at CERN. I also work with cold atoms and few-body systems.
I am responsible for the course Internship in Physics, and I have several times given the advanced course in Atomic Physics (FK7057).
Since 1 March 2024 I am subject responsible for the research educations in Physics, Theoretical Physics, Chemical Physics and Medical Radiation Physics.
My research activities split into two areas:
1. Studies of antiatoms. I am member of two collaborations at CERN, ALPHA and GBAR. Both aim at tests of fundamental matter-antimatter symmetries through comparisons of ordinary hydrogen and antihydrogen. ALPHA was the first experiment to catch an hold antiatoms in a magnetic trap (2010), and has since then made a number of studies on antihydrogen, mainly through various forms of spectroscopy. Recently, we also succeeded to make the first measurement of how antihydrogen falls towards the earth, thus ruling out some exotic theories prediciting that it would fall up. The GBAR project has just started, but will in the future also measure the gravitational acceleration of antihydrogen. Rather than using trapped antihydrogen GBAR will create antihydrogen ions (2 anti-electrons and one antiproton).
2. I am also interested in ultracold atoms (i.e. atoms cooled down to about 0.000001 degrees over the absolute zero temeprature). At these temperatures atoms behave quantum mechanically. My main area is so-called Efimov states, formed by three atoms. But I have also worked on other problems, e.g. laser cooling.
