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…
Dark-fringe interferometer with dynamic phase control for Mössbauer science
Miriam Gerharz, Dominik Lentrodt, Lars Bocklage +10
Interference is a powerful tool for measuring and control. In Mössbauer science, interference effects are essential to most applications, due to the coherent scattering nature. Ho…
Probing the Linewidth of the 12.4-keV Solid-State Sc Isomeric Resonance
Peifan Liu, Miriam Gerharz, Berit Marx-Glowna +37
The Sc nuclear transition from the ground to the isomeric state at 12.389~keV, with a lifetime of 0.46~s, exhibits an extraordinarily narrow natural width of 1.4~feV and a q…
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…
