Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
The paper reports the generation of nanofocused hard‑x‑ray attosecond pulses at the European XFEL with peak intensities around 10^20 W/cm², verified via saturation of amplified spo…
Spatio-temporal migration of antiferromagnetic domain walls in Sr2IrO4
Ian Robinson, David Yang, Ross Harder +18
By laser pump-probe time-resolved coherent magnetic X-ray diffraction imaging, we have measured the migration velocity of antiferromagnetic domain walls in the Mott insulator Sr2Ir…
Origins of suppressed self-diffusion of nanoscale constituents of a complex liquid
Christian P. N. Tanner, Vivian R. K. Wall, Mumtaz Gababa +25
Understanding and ultimately controlling the transformations and properties of nanoscale systems, from proteins to synthetic nanomaterial assemblies, is limited by the inability to…
Single-shot sorting of Mössbauer time-domain data at X-ray free-electron lasers
Miriam Gerharz, Willi Hippler, Berit Marx-Glowna +28
Mössbauer spectroscopy is widely used to study structure and dynamics of matter with remarkably high energy resolution, provided by the narrow nuclear resonance line widths. Howev…
Ultrafast heat transfer in single palladium nanocrystals seen with an X-ray free-electron laser
David Yang, James Wrigley, Jack Griffiths +11
We report transient highly strained structural states in individual palladium (Pd) nanocrystals, electronically heated using an optical laser, which precede their uniform thermal e…
Coherent X-rays reveal anomalous molecular diffusion and cage effects in crowded protein solutions
Anita Girelli, Maddalena Bin, Mariia Filianina +38
Understanding protein motion within the cell is crucial for predicting reaction rates and macromolecular transport in the cytoplasm. A key question is how crowded environments affe…
