Complex Attosecond Waveform Synthesis at FEL FERMI Open
Free-electron lasers (FELs) can produce radiation in the short wavelength range extending from the extreme ultraviolet (XUV) to the X-rays with a few to a few tens of femtoseconds pulse duration. These facilities have enabled significant b…

Analysis of two-color photoelectron spectroscopy for attosecond metrology at seeded free-electron lasers Open
The generation of attosecond pulse trains at free-electron lasers opens new opportunities in ultrafast science, as it gives access, for the first time, to reproducible, programmable, extreme ultraviolet (XUV) waveforms with high intensity.…

Resonant propagation of x rays from the linear to the nonlinear regime Open
We present a theoretical study of temporal, spectral, and spatial reshaping of intense, ultrafast x-ray pulses propagating through a resonant medium. Our calculations are based on the solution of a three-dimensional time-dependent Schrodin…

Photoemission delays in 2D model molecules Open
Synopsis Photoelectron spectroscopy is one of the main techniques used to probe matter since the understand-ing of the photoelectric effect. Within the last decade, a new aspect has been given to spectroscopy, revisiting it in the time dom…

Opto-optical modulator (OOM) for extreme ultraviolet pulses Open
Synopsis There is a profound, almost symbiotic relation between electrons and photons. When light interacts with matter the electrons in the material will start to move and oscillate. When a charged particle, such as an electron, oscillate…

Probing Stark-induced nonlinear phase variation with opto-optical modulation Open
We extend the recently developed technique of opto-optical modulation (OOM) to probe state-resolved ac-Stark-induced phase variations of a coherently excited ensemble of helium atoms. In a joint experimental and theoretical study, we find …

Dynamical distortions of structural signatures in molecular high-order harmonic spectroscopy Open
We study the signature of two-center interferences in molecular high-order harmonic spectra, with an emphasis on the spectral phase. With the help of both ab initio computations based on the time-dependent Schr\"odinger equation and the mo…

Optimal Basis Set for Electron Dynamics in Strong Laser Fields: The case of Molecular Ion H<sub>2</sub><sup>+</sup> Open
A clear understanding of the mechanisms that control the electron dynamics in a strong laser field is still a challenge that requires interpretation by advanced theory. Development of accurate theoretical and computational methods, able to…
