报告摘要:
Ultrafast X-ray spectroscopy allows the study of light-matter interaction with unprecedented temporal and spatial resolution with the further advantages of being element-selective and oxidation- and spin-state specific. The investigation of the properties of core electrons at ultrafast time scales promises to enlighten the dynamics occurring in complex materials. I will present the recent developments we implemented toward attosecond X-ray spectroscopy based on tabletop sources, such as a bright XUV source based on high-order harmonic generation in microchannels and a mid-IR driving source for harmonic spectroscopy.
报告人介绍:
Caterina Vozzi is Research Director of the Italian National Research Council (CNR). She leads the Ultrafast Molecular Imaging group at the Institute of Photonics and Nanotechnologies. She obtained her PhD in Physics from Università degli Studi di Milano in 2005. She was hired as a Research Officer by CNR in 2009. In 2010 she spent a year as a visiting scientist in the group of Prof. Paul Corkum at the Steacie Institute for Molecular Sciences of the National Research Council of Canada in Ottawa. Her research interests focuses on atomic and molecular physics, and in particular on the physics and applications of high-order harmonic generation in noble gases, molecules and clusters, in the generation and characterization of isolated attosecond pulses, in high-order harmonic spectroscopy and in the development of high energy parametric sources for strong field applications.
