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…
X-ray Coherent Attosecond Pulse Pair Spectroscopy
Zain Abhari, Thomas M. Linker, Thomas Kroll +14
X-ray free electron laser (XFEL) experiments using self-amplified spontaneous emission (SASE) pulses typically achieve temporal resolutions of order several femtoseconds, as the pu…
Probing keV mass QCD axions with the SACLA X-ray free electron laser
Charles Heaton, Jack W. D. Halliday, Taito Osaka +12
Axions are hypothetical particles, proposed to account for the invariance of CP symmetry in quantum chromodynamics. While axions and axion-like-particles are well-motivated by stri…
Fluorescence intensity correlations enable 3D imaging without sample rotations
Robert G. Radloff, Felix F. Zimmermann, Siqi Li +23
Lensless X-ray imaging provides element-specific nanoscale insights into thick samples beyond the reach of conventional light and electron microscopy. Coherent diffraction imaging…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
From Continuous to First-Order-Like: Amorphous-to-Amorphous Transition in Phase-Change Materials
Tomoki Fujita, Yoshio Kono, Yuhan Chen +13
Polymorphism is ubiquitous in crystalline solids. Amorphous solids, such as glassy water and silicon, may undergo amorphous-to-amorphous transitions (AATs). The nature of AATs rema…
