The research groups in Physics focus on fundamental and applied atomic spectroscopy, in particular atomic structure and atom-light interaction. Applications range from atomic nucleus characterization and cancer treatments to galactic evolution.

The group performs quantum structure calculations, develops computational methods and computer programs, and determines atomic data based on Fourier transform spectroscopy and atomic lifetime measurements. The data is applied to a variety of research questions, for example in the field of medicine and astronomy.

We work in the following fields:

Fundamental physics

Combining calculated atomic data with results from high-precision measurements at for example radioactive beam facilities such as ISOLDE at CERN (link:, nuclear properties are extracted for unexplored parts of the nuclear chart. These data, in turn, are important for nuclear theory.

Atomic Astrophysics

Over 99% of all visible matter in the Universe is in the plasma state. The group determines atomic data needed to analyze spectra from the plasma and to give information about its fundamental properties, e.g., temperature and density, as well as the abundance and isotopic composition of different elements and the balance between different ionization stages. Data on abundances are used to test different models of nucleosynthesis in the stars and trace the chemical evolution of the galaxy. In addition, there are important applications for future energy sources such as fusion reactors.

Data for Medicine

The group produces data and develops computer programs needed for dosimetry simulations for new cancer treatments based on the emission of low-energetic Auger electrons. The data and the simulation programs aim for accurate dose determinations at the microscale.

The research groups are active in national and international networks, e.g. in the development of atomic calculations and running the Edlén FTS laboratory as well as using astronomical observational facilities. We are in addition part of the consortium behind the DESIREE national facility for studies of cold atoms, and CompAS and LUMCAS networks.
