报告摘要：The natural time scale of atoms in action is of the order of femtoseconds(1 fs = 10-15 s).Ahmed Zewail opened a route to study chemistry that occurs in the femtosecond regime and received a Nobel prize in 1999. This field has been significantly expanded in the last decade thanks to the advances of X-ray free electron lasers (FELs). This lecture describes status of dynamic molecular imaging originally established with synchrotron radiation sources but now becoming realistic tools for shooting molecular movies for isolated molecules in photochemical reaction with femtosecond pulses.
The natural time scale of electrons in action is of the order of attoseconds(1 as =10-18 s). The Nobel prize of physics in 2023 was awarded to this field of attosecond science. Recent developments of generating attosecond pulses both in the laboratories and free electron laser facilities make an intangible dream of watching electrons in action a tangible reality. This lecture describes recent activities of catching attosecond motion of an electron or an electron hole with attosecond pulses.
