报告人简介：

Jochen Küpper is the professor of Physics and Professor by courtesy of Chemistry at the University of Hamburg, Germany. He is best known for his pioneering work on the control of complex neutral molecules, including the spatial separation of structural isomers and their laser-alignment and mixed-field orientation. He develops novel techniques to control the external and internal degrees of freedom of neutral molecules and exploits these well-defined samples in experiments to image their nuclear and electronic structure and dynamics.

摘要：

Observing molecules in action through the recording of “molecular movies”, i. e., their spatiotemporal evolution during chemical dynamics, with atomic spatial and temporal resolution could revolutionize our understanding of the molecular sciences. Wel build upon our approaches to prepare highly controlled samples that enable advanced imaging methods of individual molecular species and directly in the molecular frame. Here, I will discuss the application of diffractive imaging for the recording of such movies with few-picometer and few-femtosecond resolution. Furthermore, I will present examples of UV-induced photochemical dynamics and the path toward the atomically resolved movies of these reactions.
