Our Research Groups

Fysikum's research is carried out in both theoretical and experimental physics. We have seven departments and several projects. We often work in collaboration and also with other universities and research institutes.

Research Projects

Physics' size and breadth puts us in a strong position when it comes to physics research. Our ambition is to deliver research results in all, or at least most, areas of physics - and at the highest level.

Publications

Our researchers and students yearly produces a large amount of publications within the area of social work. Since 2007 these are registered in DiVA, the Digital Scientific Archive for easy access.

We create a digital twin of the universe to understand the Big Bang

I try to gain a full understanding of how the universe was created 13.8 billion years ago. As a cosmologist, I have the luxury of travelling out into the universe in my mind every day and see life on Earth from a different perspective. This makes it clear how precious our little planet is.

Testing gravity with large quantum systems: what we know today

One of the greatest unsolved mysteries in physics is the unification of quantum mechanics and gravity. The core challenge arises from the fact that quantum systems, typically among the smallest physical systems, have extremely small masses. Measuring the gravitational field of such tiny masses is beyond the reach of current technology. As a result, even the seemingly simple question of how gravity behaves when a particle is in a quantum superposition remains unanswered experimentally. While numerous theoretical approaches have been proposed to unify quantum mechanics and gravity, the absence of experimental evidence makes it difficult to determine the correct path forward.

Bringing research to the lab to prove his theories

Using knowledge from one field in another can lead to unexpected breakthroughs. Wallenberg Scholar Emil Bergholtz has established a system to constantly explore new fields. The next step is to substantiate his theories within topological systems by building an extremely sensitive sensor.
