Uwe Bovensiepen

Prof. Dr. Uwe Bovensiepen is a Professor at the University of Duisburg-Essen's Faculty of Physics, where he leads the research group on Ultrafast Phenomena in Solids and at Interfaces. His research investigates microscopic interaction mechanisms between charge, lattice, and spin degrees of freedom in condensed matter, with emphasis on energy transfer and transport in nanostructures. Key areas include femtosecond electron dynamics, magnetization processes, and laser-driven phenomena, often studied using advanced techniques like time-resolved photoelectron spectroscopy and X-ray absorption.

Research interests span ultrafast dynamics in correlated materials, heterostructures, and surfaces, with focus on:

• Femtosecond spin currents and magnetization dynamics
• Element-specific analysis via ultrafast X-ray spectroscopy
• Hot electron relaxation in metallic nanostructures
• Laser-induced phase transitions and solvation dynamics

His recent publications demonstrate strong trends in ultrafast spectroscopy of quantum materials (e.g., NiO, FePt, TaS₂), development of table-top X-ray sources, and spatiotemporal electron transport. Work frequently involves collaborations with facilities like the European XFEL and employs methods ranging from MeV electron diffraction to nonlinear magneto-optics.

Prof. Bovensiepen advises a large cohort of doctoral and master's students, with current projects funded by the German Research Foundation (DFG) through collaborative initiatives like SPP 1840 Quantum Dynamics in Tailored Intense Fields and CRC 1242 Non-Equilibrium Dynamics of Condensed Matter. Laboratories under his supervision include dedicated setups for time-resolved photoelectron spectroscopy, high-power laser systems, and ultrafast electron diffraction.
