Ultrafast Dynamics in Condensed Matter


Our research focuses on ultrafast electronic, magnetic, and structural dynamics in condensed matter, and the development of new experimental methods to study these processes. In particular, we combine the advantages of ultrashort X-rays from high-harmonic generation with ultrafast solid-state research, and explore dynamics at fundamental time- and lengthscales, where all elementary processes can be captured, even at the level of electrons. Current topics involve the study of electronic properties and dynamics in correlated-electron materials, at surfaces and interfaces, in nanostructures, and metal-adsorbate hybrid systems.

08/2017: Dr. Sabine Steil is awarded with a Dorothea-Schlözer PostDoc fellowship
Dr. Sabine Steil is awarded with a Dorothea-Schlözer PostDoc fellowship for the coming two years. These positions are awarded to further develop independent research and prepare future third-party funding (Information about the Dorothea-Schlözer Fellowship). Congratulations!

06/2017: Award of the Robert-Wichard-Pohl medal for excellence in teaching
Prof. Mathias was awarded the Robert Wiechard Pohl medal for his lecture "Introduction to solid state physics" by the faculty of physics for excellence in teaching (Information about the price). We feel deeply honored by this prize and will strive to further excel in teaching.

05/2017: CRC1073 continues - AG Mathias with two projects in second funding period
The CRC1073 "Atomic scale control of energy conversion" enters its second funding period in July 2017. Our group participates with projects studying elemental steps of energy conversion after strong optical excitation in correlated materials (together with AG Kehrein) and the active control of energy conversion in correlated oxides by spin currents (together with AG Ulrichs)
