Attosecond x-ray scattering from a particle-hole wave packet Physical review / A 95(6), 062107 (2017) [10.1103/PhysRevA.95.062107]   We investigate the imaging of electron wave-packet dynamics by measuring the pattern of inelastically scattered photons. For this purpose, we develop a theory of time-resolved Compton scattering [...] OpenAccess: PDF PDF (PDFA); 2017-06-0114:22 [PUBDB-2017-04151] Journal Article et al Femtosecond response of polyatomic molecules to ultra-intense hard X-rays Nature 546(7656), 129 - 132 (2017) [10.1038/nature22373]   X-ray free-electron lasers enable the investigation of the structure and dynamics of diverse systems, including atoms, molecules, nanocrystals and single bioparticles, under extreme conditions1, 2, 3, 4, 5, 6, 7. Many imaging applications that target biological systems and complex materials use hard X-ray pulses with extremely high peak intensities (exceeding 1020 watts per square centimetre)3, 5.

Thereby, we investigate the photoelectron circular dichroism (PECD) for nearly symmetric O 1s and F 1s electronic orbitals, which are localized on different molecular sites [...] OpenAccess: PDF PDF (PDFA); 2017-06-0108:59 [PUBDB-2017-04130] Journal Article et al Influence of model parameters on a simulation of x-ray irradiated materials: example of XTANT code SPIE Optics + Optoelectronics, Meeting locationPrague, Czech Republic, Proceedings of SPIE 10236, 102360I (2017) [10.1117/12.2266953]   In this contribution an analysis of influence of model parameters on the results of simulations of material properties under free-electron laser irradiation is presented.

Correlation-driven charge migration following double ionization and attosecond transient absorption spectroscopy Physical review / A 95(5), 053411 (2017) [10.1103/PhysRevA.95.053411]   We theoretically investigate charge migration following prompt double ionization. Thereby, we extend the concept of correlation-driven charge migration, which was introduced by Cederbaum and coworkers for single ionization [Chem.

This is achieved by means of a femtosecond infrared laser pulse interacting with the N_{2}$$^{2+}$ dication produced by the x-ray pulse [...] OpenAccess: PDF; 2017-04-1809:40 [PUBDB-2017-01674] Journal Article Santra, R. Interplay between relativistic energy corrections and resonant excitations in x-ray multiphoton ionization dynamics of Xe atoms Physical review / A 95(4), 043412 (2017) [10.1103/PhysRevA.95.043412]   In this paper, we theoretically study x-ray multiphoton ionization dynamics of heavy atoms taking into account relativistic and resonance effects. When an atom is exposed to an intense x-ray pulse generated by an x-ray free-electron laser (XFEL), it is ionized to a highly charged ion via a sequence of single-photon ionization and accompanying relaxation processes, and its final charge state is limited by the last ionic state that can be ionized by a single-photon ionization [...] OpenAccess: PDF;
