Description of the thesis topic
This project deals with the study of complex charged molecules (biomolecules) using ultrashort femto and attosecond XUV pulses. The goal of the project is to understand the first steps of the ultrafast dynamics following a high energy photoexcitation process and the role played by hole, proton, energy and structural dynamics. To do so, pump-probe experiments will be performed using a very innovative experimental set up that will be further developed during the project.
Recent advances in ultrafast science make it possible to use ultrashort UVX pulses to probe matter on femto and attosecond time scales. At these time scales it is possible to probe the dynamics of charges, energy and structural changes following photo excitation. The ILM is a laboratory located in Lyon whose activity is highly interdisciplinary. It dominates expertise at the highest international level in experience and theory, from optics to molecular physics, from materials to soft matter. The ILM's DYNAMO group is developing a leading activity for the study of molecular matter using new generation of light sources. Since the emergence of attosecond sciences in the early 2000s, the group has contributed to the development of experiments applied to molecular systems. He is internationally recognized for his studies which extend these techniques to increasingly complex molecules. The candidate will work on an experimental device unique in the world and on a new type of experiments combining the production of complex molecular ions, attosecond XUV pulse and electron spectrometry. The candidate must hold a master degree in physics and/or chemistry and have a strong interest in molecular sciences and/or optics.
