Research at the department

In Uppsala you will find Sweden’s perhaps largest research effort in physics and astronomy. The research includes string theory, particle physics and nuclear physics, atomic physics and material science, as well as studies of the origin of the planetary system and the universe itself.

Basic research aimed at revealing the fundamental laws of Nature and finding our place in the universe, is found side by side with applied research on new materials and energy technology. Uppsala is an active participant in a large number of leading international research collaborations such as CERN, ESO, ESA, AMANDA and MAXLab. Over the years Uppsala has been awarded two Nobelprizes through Manne Siegbahn and his son Kai Siegbahn.

Applied Nuclear Physics

In Applied Nuclear Physics experimental research is performed in the fields of present and future nuclear energy production with an emphasis on diagnostics and nuclear data.

Astronomy and Space Physics

The astronomical research in Uppsala ranges from planetary systems, stellar physics, to the large scale structure of the Universe. Theoretical and observational research is complemented with development of instruments.


FREIA is a large scale facility for research and development of new
accelerators and instrumentation for accelerator based research.

High Energy Physics

Materials Physics

The exploration of dimensionality aspects of phase transitions as well as all advanced production of devices requires good knowledge of materials. That knowledge is our mission.

Materials Theory

The activities at the Division of Materials Theory cover a wide range of topics within materials and condensed matter physics, including magnetism, superconductivity, the physics of the Earth's deep interior, nanoscale physics, hydrogen storage and biological physics.

Molecular and Condensed Matter Physics

We have a broad research scope based on experimental studies of the electronic structure of matter. Motivated by issues such as energy, environment as well as fundamental topics, we investigate systems ranging from free atomic, molecular and cluster species to liquids, molecular materials and single crystal hard materials with synchrotron-radiation-based spectroscopies as our main tools.

Nuclear Physics

Physics Education Research

The activities of the group are centred principally around the interplays between learning and the form and content of physics and related engineering curricula and teaching.

Theoretical physics

The research in theoretical physics spans a large spectrum of physical problems, from the origin of the universe, where both the forces and matter are represented by oscillating strings, via proteins that fold and form knots, to the structure of the particles colliding in our accelerators.

Searching for Chemical Signatures in the Milky Way: The AMBRE Project & the Gaia-ESO Survey

Astronomy and Space Physics

Large scale spectroscopic programmes are significantly advancing the studies of the chemical and dynamic evolution and formation of the Milky Way. I will present here the results thus far of the AMBRE Project, an ambitious project to provide stellar parameters for all FGKM stars within the ESO Archive. While primarily undertaken to provide a higher level of information for searches within the ESO archive, I will present the various science verification outcomes from this extensive dataset. In particular extracting key samples of globular cluster and open cluster stars to explore the relations in metallicity and alpha element abundances derived from this homogeneous analysis.

Modern Methods in Amplitudes III

Theoretical Physics

Scattering amplitudes can be computed with Feynman rules but that is not always the most convenient method and a lot of more efficient techniques are known. I will go through the basics of scattering amplitudes and explain the BCFW recursion relations which is very useful at loop level, then go on to discuss generalized unitarity which can be used to piece together loop-level amplitudes from tree-level amplitudes. Finally, I'll go through some of the basics concerning twistor string theories and the Grassmanian formulation of scattering amplitudes in N=4 SYM.
