The big picture

Photochemical and photophysical phenomena are involved in a wide range of processes, including photosynthesis, the initial steps in human vision, and emerging nanotechnologies such as light-driven molecular motors. The time scales involved are very short, and the dynamics is predominantly quantum mechanical.

The quantum nature of our world at the microscopic level provides opportunities to accomplish new feats of science and engineering, unthinkable in our everyday classical world. Examples include quantum computing, coherent control of chemical reactions, photonics, and the design of new materials with interesting and useful properties. Ultimately, we hope our research will contribute to the development of new technologies that are more efficient and require less resources.


Our goals

Our long-term goal is to develop theory and simulations to a degree that makes it possible to design, from scratch, novel photochemical and photophysical processes for the quantum technologies of the future. This work involves the development of new theoretical and computational methods in close collaboration with new experiments; our mantra is new theory for new experiments.

Many of our projects are done in close collaboration with experimental groups that work on new light-sources, such as ultrafast lasers and free-electron x-ray lasers.


Ongoing projects:

1. Ultrafast scattering ("molecular movies")

2. Photoelectron and high harmonic generation spectroscopy

3. Heavy Rydberg states and superexcited molecules
