报告摘要：
The generation of attosecond XUV pulses in the first decade of 21st century has opened the new field of attosecond physics. Such ultrashort pulses have enabled probing and controlling of ultrafast electron dynamics in atoms and molecules, for the first time in history.  In this talk, I will discuss what we have learnt on using attosecond XUV pulses to probe/control ultrafast processes in atomic and molecular physics. The topics include the proposed attosecond pump-probe technique (a “holy-grail” attosecond experiment) that can be used to map-out the ultrafast electron motion inside atoms, the attosecond photoelectron microscopy for probing transient molecular structures, as well as the attosecond control of electron-electron correlation in photo-ionization of atoms. Finally, I will envision, from a theorist’s point of view, what directions we might work toward defining “killer-apps” of attosecond XUV pulses.  

报告人简介:

Dr. Suxing Hu is a Senior Scientist and the Group Leader of the theoretical high-energy-density physics group at the Laboratory for Laser Energetics (LLE), University of Rochester. He started theoretical studies on how intense laser pulse interacts with atoms, molecules, and clusters in late-1990’s supervised by Prof. Zhizhan Xu. He got his PhD in physics from Chinese Academy of Sciences, at Shanghai Institute of Optics and Fine Mechanics in 1998. After graduation, he took the Alexander von Humboldt Fellowship and continued his AMO physics researches at University of Freiburg and Max-Born-Institute in Berlin. Suxing moved to the US in 2001 as a postdoc research associate at University of Nebraska-Lincoln. Late on he became a Director’s Postdoc Fellow at Los Alamos National Laboratory. He joined in LLE as a scientist in 2006 and became a senior scientist in 2013.  As a theoretician, he is interested in understanding how matters behave under extreme conditions such as under ultra-high pressures and in super-strong/ultrafast fields. Suxing was awarded The Hundred Outstanding Doctorate Thesis Prize by China’s Department of Education in 2000, among other prizes. Suxing has published over ~160 articles on top-ranked physics journals, including Nature Communications and 32 Physical Review Letters of which 12 PRLs are first-authored, which receive over ~4200 citations so far. For his contributions to attosecond physics, he was elected a Fellow of the American Physical Society in 2013.
