Characterization of attosecond pulses in the soft x-ray regime
Stefan Pabst, Jan Marcus Dahlström
Attosecond x-ray pulses offer unprecedented opportunities for probing and triggering new types of ultrafast motion. At the same time, pulse characterization of x-rays presents new…
Probe of Multi-electron Dynamics in Xenon by Caustics in High Order Harmonic Generation
Davide Faccialà, Stefan Pabst, Barry D. Bruner +8
We investigated the giant resonance in Xenon by high-order harmonic generation spectroscopy driven by a two-color field. The addition of a non-perturbative second harmonic componen…
Collective resonances of atomic xenon from the linear to the nonlinear regime
Yi-Jen Chen, Stefan Pabst, Robin Santra
XUV nonlinear spectroscopy has recently discovered that there is more than one collective dipole resonance state in the energy range of the giant dipole resonance (GDR) of atomic X…
Driving Rabi oscillations at the giant dipole resonance in xenon
Stefan Pabst, Daochen Wang, Robin Santra
Free-electron lasers (FELs) produce short and very intense light pulses in the XUV and x-ray regimes. We investigate the possibility to drive Rabi oscillations in xenon with an int…
Can strong-field ionization prepare attosecond dynamics?
Stefan Pabst, Hans Jakob Wörner
Strong-field ionization (SFI) has been shown to prepare wave packets with few-femtosecond periods. Here, we explore whether this technique can be extended to the attosecond time sc…
Theoretical characterization of the collective resonance states underlying the xenon giant dipole resonance
Yi-Jen Chen, Stefan Pabst, Antonia Karamatskou +1
We present a detailed theoretical characterization of the two fundamental collective resonances underlying the xenon giant dipole resonance (GDR). This is achieved consistently by…
