Hans-Hermann Ritze

Dr. Hans-Hermann Ritze is a theoretical researcher at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin, Germany, where he leads the Attosecond Theory Group (T1) from House A, room 2.09. Contact is available via hans-hermann.ritze@mbi-berlin.de or +49 30 6392 1239. His work bridges quantum chemistry and ultrafast laser physics with experimental collaborators.

His research centers on theoretical modeling of excited-state dynamics in biomolecules and nanostructures using attosecond spectroscopy techniques. Key focus areas include hydration effects on DNA base photostability (thymine, guanosine, adenine), proton transfer mechanisms, and fragmentation dynamics under intense laser fields. He integrates quantum simulations with time-resolved photoelectron spectroscopy to unravel non-adiabatic processes at femtosecond timescales.

Analysis of his 2009-2015 publications reveals consistent investigation of photophysical relaxation pathways in aqueous environments, particularly how solvent interactions modulate excited-state lifetimes in nucleobases. His group specializes in simulating liquid-jet photoelectron spectra and modeling laser-induced dynamics in clusters like hydrated adenine and C60 fullerenes.

Dr. Ritze has no listed scientific awards in the provided materials. While student advising isn't documented, his collaborative publications span multiple institutions including Fritz Haber Institute and University of Tokyo. He directs the Attosecond Theory Group at MBI, focusing on computational frameworks for electron-nuclear dynamics in photoionization and dissociation processes.
