报告摘要

It is well known that Fano resonances are ubiquitous in atoms, molecules and condensed materials. They have been observed since the 1930's. These resonances are characterized by narrow widths and they have lifetimes of the order from a few tens of meVs down, corresponding to lifetimes of the order from a few femtoseconds to longer ones. With the emergence of attosecond pulses, is it possible to monitor, or observe the building up of a Fano resonance in the time domain? Since electronic detectors available today can not be measure anything shorter than a few picoseconds, how can one observe the buildup of a Fano resonance? [Ref: Science 354, 738 (2016)]

 

报告人简介:Prof. Lin is now University Distinguished Professor at Kansas State University and Associate Director of the J. R. Macdonald Laboratory. He received Ph. D. from University of Chicago in 1974 after he got bachelor degree at National Taiwan University in 1969. He has done a lot of important work in different topics in AMO.
