An overview of both experimental and theoretical results in the field of resonant scattering of
tunable soft and hard x-ray radiation is presented, with a main focus on the closely related …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

When materials are exposed to X-ray pulses with sufficiently high intensity, various
nonlinear effects can occur. The most fundamental one consists of stimulated electronic …

The advent of free-electron lasers (FELs) in the soft-and hard-x-ray spectral regions has
introduced the possibility to probe electronic, magnetic, and structural dynamics, in both …

Fourier transform holography (FTH) is a lensless imaging technique where the wave
scattered by an object is superimposed with the wave scattered by a reference source …

Femtosecond transient soft X-ray absorption spectroscopy (XAS) is a very promising
technique that can be employed at X-ray free-electron lasers (FELs) to investigate out-of …

We systematically study the fluence dependence of the resonant scattering cross-section
from magnetic domains in Co/Pd-based multilayers. Samples are probed with single …

Resonant X-ray absorption, where an X-ray photon excites a core electron into an
unoccupied valence state, is an essential process in many standard X-ray spectroscopies …

To shorten the duration of x-ray pulses, we present a nonlinear optical technique using
atoms with core-hole vacancies (core-hole atoms) generated by inner-shell photoionization …

The nature of light, extending from the optical to the x-ray regime, is reviewed from a
diffraction point of view by comparing field-based statistical optics and photon-based …
