Title: Attosecond electron beams for ultrafast chemical imaging

Speaker: Dr. Yuya Morimoto, Pioneering Research Institute and RIKEN center for Advanced Photonics, RIKEN, Japan

Abstract:
With the advent of attosecond lasers, it has become possible to observe the motion of electrons inside matter in real time. However, due to the limitation of wavelength, it is still challenging to observe electronic motions resolved in space. In this talk, I will introduce our recent efforts towards attosecond and Angstrom imaging of electronic dynamics with electron beams. The methods for the generation and characterization of attosecond electron beams are presented. I will also introduce our recent experimental results on the attosecond electron diffraction of a single-crystalline membrane and the field-induced rocking curve effect. At the end of the talk, I will give an overview of on-going theoretical research on the scattering of ultrashort electron pulses conducted jointly with Prof. Madsen.
