Near-perfect efficiency in X-ray phase microtomography

Dominik John, Gregor Breitenhuber, Sami Wirtensohn +8

X-ray microtomography at synchrotron sources is fundamentally limited by the high radiation dose applied to the samples, which restricts investigations to non-native tissue states…

HoToPy: A toolbox for X-ray holo-tomography in Python

Jens Lucht, Paul Meyer, Leon Merten Lohse +1

We present a Python toolbox for holographic and tomographic X-ray imaging. It comprises a collection of phase retrieval algorithms for the deeply holographic and direct contrast im…

Three-phase contact line dynamics on moving fibers measured by X-ray holography

Louisa E. Kraft, Jens Lucht, Fiona Berner +9

Wetting of solid surfaces by a liquid is important for many natural and industrial processes such as printing, painting and coating. However, a quantitative description of the dyna…

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…
