Probing the formation of femtosecond laser-induced periodic surface structures on silica films by ultrafast small-angle X-ray scattering

Dominik Kaczmarek, Jean-Luc Déziel, Thies Johannes Albert +16

Ultrashort X-ray pulses, as provided by X-ray Free Electron Lasers (XFELs), offer unique opportunities to probe the formation of laser-induced nanostructures with sizes even below…

Picosecond localization dynamics following ultrafast nanoscale magnetic switching

Daniel Metternich, Michael Schneider, Giuseppe Mercurio +28

Ultrashort laser pulses provide the fastest known way to switch magnetic order. Such excitation commonly creates nanometer-scale domains, even after homogeneous illumination when t…

Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor

Daniel Jost, Jiarui Li, Jordyn Hales +21

Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…

Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering

Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32

Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…

Ultrafast decoupling of polarization and strain in ferroelectric BaTiO

Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20

A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…

Analysis of long-lived effects in high-repetition-rate stroboscopic transient X-ray absorption experiments on thin films

Tobias Lojewski, Loïc Le Guyader, Naman Agarwal +41

Time-resolved X-ray absorption spectroscopy (tr-XAS) has been shown to be a versatile measurement technique for investigating non-equilibrium dynamics. Novel X-ray free electron la…

The Heisenberg-RIXS instrument at the European XFEL

Justine Schlappa, Giacomo Ghiringhelli, Benjamin E. Van Kuiken +44

Resonant Inelastic X-ray Scattering (RIXS) is an ideal X-ray spectroscopy method to push the combination of energy and time resolutions to the Fourier transform ultimate limit, bec…

Femtosecond spin-state switching dynamics of spin-crossover molecules condensed in thin films

Lea Kämmerer, Gérald Kämmerer, Manuel Gruber +22

The photoinduced switching of Fe(II)-based spin-crossover complexes from singlet to quintet takes place at ultrafast time scales. This a priori spin-forbidden transition triggered…
