报告题目: Catching and steering electrons in action by light
报告摘要: The natural time scale of electrons in action is of the order of attoseconds (1 as =10-18s). 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 the Nobel prize of physics this year was awarded to this field of attosecond science. Generations of isolated attosecond pulses in the soft X-ray regime at at LCLS in the USA opens a new route to measure molecular core-level photoionization time delays that occurs in the attosecond timescale. Generations of two-colour attosecond pulses at LCLS opened the door to watch the electron (charge) in action in a molecule that occurs in the attosecond timescale. Generating phase-coherent multi-colour pulses at FERMI, on the hand, provided a novel approach to coherently control the electronic wave-packet and to read out the photoionization phase, or attosecond photoionization time delay. The talk will also address the titled study with laboratory attosecond pulse train light sources, complementary to FELs, combined with combined with REMI/COLTRIMS. I acknowledge all the collaborators in the authors list for fruitful collaborations.
