Research groups

Research at the Atomic Physics division

The division pursues several different lines of research in Atomic, Molecular and Optical Physics. In some cases the activities combine experimental, theoretical, and computational work. For example, the research on interactions involving atoms, molecules, and clusters at DESIREE and other facilities, is complemented by model developments and computations.


Action Spectroscopy Heroes

Mark H. Stockett’s research combines optical spectroscopy with mass spectrometry to unravel the photo-physics of complex molecules.


Antihydrogen and few-body physics

We are theory partners in two antihydrogen collaborations, ALPHA and GBAR at CERN, with the aim to study fundamental symmetries using antimatter. We also study properties of Efimov states, which are three-body states with peculiar quantum properties.

Atomic many-body theory for structure and dynamics

We build theoretical and computational tools for the interpretation and quantitative description of experimental observations - in particular those made with attosecond light sources.

Desiree accelerator

DESIREE research

We lead the work on DESIREE (Double ElectroStatic Ion Ring ExpEriment), which is a new research facility at the Department of Physics, Stockholm University. The main instrument of this facility is a world unique cryogenically cooled double ion-beam storage ring.

Spacey molecules

Gas phase molecular dynamics

We study how complex molecular systems such as e.g. fullerenes, PAHs, biomolecules, and clusters respond to energetic processing (ion/atom/molecule/photon impact).


Quantum molecular dynamics

We perform theoretical studies of molecular reactions that require a solid quantum description of both electrons and nuclei. These processes involve reactions driven by electron-molecule collisions, colliding atoms or ions, as well as photon-induced processes. The reactions have in common that highly excited states are involved and the motions of the electrons and nuclei cannot be treated separately.
