报告内容简介：
The talk will first illustrate status of the titled study with short-wavelength free-electron lasers (FELs), focusing on characteristic properties of different facilities. The first high repetition rate soft X-ray FEL, European XFEL, combined with REMI/COLTRIMS, made a long-standing dream to watch atoms in action, initiated by photoexcitation of a molecule, a tangible reality [1]. Generations of two-colour attosecond pulses at LCLS in the USA opened the door to watch charge in action that occurs in the attosecond timescale [2]. Generating phase-coherent multi-colour pulses at FERMI, on the hand, provided a novel approach to coherently control the electronic wave-packet [3] and to read out the photoionization phase, or attosecond photoionization time delay [4]. The talk will also address the titled study with laboratory attosecond pulse train light sources, complementary to FELs, combined with combined with REMI/COLTRIMS [5,6]. I acknowledge all the collaborators in the authors list of [1-6] for fruitful collaborations.
