Phonons and magnetism of kagome FeGe probed by nuclear resonant scattering
Yu Tang, Saizheng Cao, Sijie Xu +6
Kagome FeGe hosts a charge-density wave (CDW) that strongly interplays with antiferromagnetic order. Here, we report Fe nuclear resonant scattering measure…
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…
Energy Time Ptychography for one-dimensional phase retrieval
Ankita Negi, Leon Merten Lohse, Sven Velten +9
Phase retrieval is at the heart of adaptive optics and modern high-resolution imaging. Without phase information, optical systems are limited to intensity-only measurements, hinder…
Collective nuclear excitation and pulse propagation in single-mode x-ray waveguides
Leon M. Lohse, Petar AndrejiÄ, Sven Velten +8
Waveguides offer a means to controllably couple atomic ensembles to the electromagnetic field therein. Here, we demonstrate x-ray propagation in planar thin-film waveguides coupled…
