Simultaneous two-color snapshot view on ultrafast charge and spin dynamics in a Fe-Cu-Ni tri-layer
Benedikt Rösner, Boris Vodungbo, Valentin Chardonnet +19
Ultrafast phenomena on a femtosecond timescale are commonly examined by pump-probe experiments. This implies multiple measurements where the sample under investigation is pumped wi…
Symmetry allows for distinguishability in totally destructive many-particle interference
Julian Münzberg, Christoph Dittel, Maxime Lebugle +4
We investigate, in a four photon interference experiment in a laser-written waveguide structure, how symmetries control the suppression of many-body output events of a unitar…
Bloch Oscillations of Einstein-Podolsky-Rosen States
Maxime Lebugle, Markus Gräfe, René Heilmann +3
Bloch Oscillations (BOs) of quantum particles manifest themselves as periodic spreading and re-localization of the associated wave functions when traversing lattice potentials subj…
Time-Resolved XUV absorption spectroscopy and magnetic circular dichroism at the Ni -edges
Marcel Hennes, Benedikt Rösner, Valentin Chardonnet +21
Ultrashort optical pulses can trigger a variety of non-equilibrium processes in magnetic thin films affecting electrons and spins on femtosecond timescales. In order to probe the c…
Tunable kinoform x-ray beam splitter
Maxime Lebugle, Gediminas Seniutinas, Felix Marschall +3
We demonstrate an x-ray beam splitter with high performances for multi-kilo-electron-volt photons. The device is based on diffraction on kinoform structures, which overcome the lim…
Implementation of Quantum and Classical Discrete Fractional Fourier Transforms
Steffen Weimann, Armando Perez-Leija, Maxime Lebugle +9
Fourier transforms are ubiquitous mathematical tools in basic and applied sciences. We here report classical and quantum optical realizations of the discrete fractional Fourier tra…
