Modeling of Complex Systems

Group Leader: Prof. Dr. Beata Ziaja-Motyka

 

The Modeling of Complex Systems subgroup explores how the unique properties of X-ray free-electron laser radiation may be employed to characterize and modify extended atomic or molecular assemblies. Among our research interests are:

1. Radiation-Induced Changes in Complex Systems.

The X-ray flashes from a free-electron laser will enable novel 3D insight into the nanoworld and thus shed light on future technological applications. The theoretical goal is to investigate ultrafast transformations in solids induced by intense radiation, such as changes of optical and magnetic properties of materials, and formation of defects.

2. Diffraction Imaging Techniques.

Using the X-ray flashes from a free-electron laser, scientists can uncover the atomic structure of biomolecules, cell constituents, and viruses. This provides the basis for future medical breakthroughs. Research by the theory group is focused on novel techniques to retrieve static and dynamic information on the structure of the imaged objects at atomic resolution.

3. Properties of Laser-Created Plasmas.

With an X-ray free-electron laser, plasmas can be created that are as hot as the interiors of giant planets. It will be possible to follow the evolution of dense plasmas in time. The theoretical research of our group concentrates on the properties of plasmas far from equilibrium, and on the high-field regime that leads to the creation of new states of matter.
