TL;DR: The experimental and modelling results establish that the ionization of a molecule is considerably enhanced compared to that of an individual heavy atom with the same absorption cross-section, and demonstrate that efficient modelling of X-ray-driven processes in complex systems at ultrahigh intensities is feasible.

TL;DR: In this paper, the Siegert-state expansion approach is applied to the solution of the time-dependent Schrodinger equation describing a model one-dimensional laser-atom interaction problem in the Kramers-Henneberger frame.

TL;DR: The authors measure the complex charge state distributions of xenon and found a reasonable agreement by comparing with the model including the relativistic and resonance effects, which provides a basis for accurate modeling of radiation damage in hard X-ray imaging experiments on targets with high-Z constituents.

TL;DR: In this paper, the role of chemical effects, such as chemical bonds and charge transfer, on the fragmentation following multiple ionization of the molecule was examined, and femtosecond-resolved X-ray pump/X-ray probe measurements were accompanied by advanced simulations.
