Research subject Cosmology, Particle Astrophysics and Strings

The University conducts a wide range of research in theoretical and experimental astroparticle physics and cosmology. Supernovae and gravitational lenses are used for distance measurements aimed at a better understanding of dark matter and dark energy.

Our research is focused on dark matter (both theory and experiment), dark energy (both theory and experiment), cosmology, string theory and general relativity.

Astroparticle Physics

In astroparticle physics we are interested in the constituents of the Universe, most notably the nature of dark matter. In our research we connect elementary particle physics, astronomy and astrophysics to explore the dark matter, both theoretically, but also phenomenologically together with experimental groups.

Holographic spacetime from simple quantum systems

Gravitation governs cosmological expansion and mass motion on Earth and in the Universe. Quantum mechanics guides other forces and properties of matter. In "holographic" theories, gravitation and matter are parallel manifestations of quantum theory.

Research
Multi-matrix models, Higgs fields and mass ratios

The particles in the Standard Model of particle physics and their masses lack explanation. It is as if we had the periodic system of elements, but not its explanation in terms of quantum mechanics and interactions of protons, neutrons and electrons.

International Women's Day 2024: Women in physics

March 8 is International Women's Day and today we want to highlight women in physics. There are many examples including Marie Curie, Maria Goeppert Mayer and Lise Meitner to Fabiola Gianotti and Lene Hau. We also mention some of the female professors of physics who belong to the Fysikum.

A Plasma Haloscope for the Post-Inflation Axion

In Fall 2022, a consortium of the Simons Foundation, the Alfred P. Sloan Foundation, the John Templeton Foundation and the Gordon and Betty Moore Foundation published a solicitation seeking to make profound advancements in physics by means of Small-Experiments of “table-top” size. The proposal “A Plasma Haloscope for the Post-Inflation Axion”, lead by the Berkely group has been announced as one of the 11 awardees among hundreds of initial proposals, for which a total of $30M over five years has been pledged by the foundations. “With this funding and also the earlier funding by the Knut and Alice Wallenberg Foundation we’re ready to start developing and building this detector that has the potential to discover axions”, says Jón Gudmundsson, senior researcher at Stockholm and current spokesperson of the ALPHA collaboration.
