1. Ultrafast Structural Changes in a Bacterial Photosynthetic Reaction Center probed with XFEL Radiation
Abstract : Photosynthesis is the process by which plants and many species of bacteria convert energy from sunlight into chemical energy used to power their metabolism. As these plants and bacteria are eaten, the chemical energy moves up the food chain and thus photosynthesis provides fuel for almost all life on Earth. READ MORE

2. Spontaneous and stimulated X-ray Raman scattering
Abstract : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. READ MORE

4. Towards Single Molecule Imaging - Understanding Structural Transitions Using Ultrafast X-ray Sources and Computer Simulations
Abstract : X-ray lasers bring us into a new world in photon science by delivering extraordinarily intense beams of x-rays in very short bursts that can be more than ten billion times brighter than pulses from other x-ray sources. These lasers find applications in sciences ranging from astrophysics to structural biology, and could allow us to obtain images of single macromolecules when these are injected into the x-ray beam.

5. Simulations of Biomolecular Fragmentation and Diffraction with Ultrafast X-ray Lasers
Abstract : Studies of biomolecules have recently seen substantial developments. New X-ray lasers allow for high-resolution imaging of protein crystals too small for conventional X-ray crystallography. Even structures of single particles have been determined at lower resolutions with these new sources. READ MORE
