题目：Photoelectron holography and redshift in high-order harmonic generation spectra
报告人：卞学滨研究员（中国科学院武汉物理和数学研究所）
This talk will provide an overview of our recent research work in strong-field physics. Ultrafast recollision processes induced by ultrashort intense lasers lead to high-order harmonic generation(HHG) and above-threshold ionization (ATI).It is found that red shift of HHG spectra occurs in resonant systems and the dissociation process of molecules. The photoelectron holography in ATI is found to be of subcycle interference dynamics, and three new interference patterns are predicted theoretically, which can be used to probe molecular structure.
