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.

Creative research environment attracts physicists and astronomers to Stockholm

In 2008, the Oskar Klein Centre in Stockholm was founded to tackle the greatest problems in astrophysics and particle physics in an interdisciplinary manner. It is now celebrated as a rich and rewarding research environment that attracts internationally leading researchers, including Nobel laureate Frank Wilczek.

Mapping molecular funnels with X-rays: precise timings of non-adiabatic excited state dynamics

Time-resolved spectroscopy is a tool that provides access to the time-scale of chemical reactions as they happen. With the help of ultra-short light pulses, it is possible to observe conformal changes in molecules on the time-scale of the atomic motion and electronic motion. Photochemical reactions, such as the damage of DNA by means of sunlight or the key-step in the process of vision, can thus be observed in great detail.

Yet another breakthrough for researchers at DESIREE!

An international collaboration led by Mark H. Stockett (Fysikum) and James N. Bull (University of East Anglia) last week published results from experiments conducted at the DESIREE infrastructure at Fysikum in Nature Communications. After decades of speculation and searching, astronomers have recently begun to identify complex Polycyclic Aromatic Hydrocarbon (PAH) molecules in interstellar clouds.

Liquid-liquid phase separation in supercooled water from ultrafast heating of low-density amorphous

Recent experiments continue to find evidence for a liquid-liquid phase transition (LLPT) in supercooled water, which would unify our understanding of the anomalous properties of liquid water and amorphous ice. These experiments are challenging because the proposed LLPT occurs under extreme metastable conditions where the liquid freezes to a crystal on a very short time scale.
