Polariton spectroscopy at the diamond K-edge via X-ray parametric down-conversion
Fridtjof Kerker, Dietrich Krebs, Xenia Brockmüller +4
It has recently been shown that x-ray parametric down-conversion (XPDC) provides access to high-energy polaritons, resulting from the hybridization of down-converted photons with e…
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…
Interferometric measurement of nuclear resonant phase shift with a nanoscale Young double waveguide
Leon M. Lohse, Ankita Negi, Markus Osterhoff +6
The phase shift of an electromagnetic wave, imprinted by its interaction with atomic scatterers, is a central quantity in optics and photonics. In particular, it encodes informatio…
Collective nuclear excitation and pulse propagation in single-mode x-ray waveguides
Leon M. Lohse, Petar Andrejić, 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…
