Coherent x-ray-optical control of nuclear excitons with zeptosecond phase-stability
K. P. Heeg, A. Kaldun, C. Strohm +11
Coherent control of quantum dynamics is key to a multitude of fundamental studies and applications alike. In the visible or longer-wavelength domains, near-resonant light fields ha…
Ab initio quantum models for thin-film x-ray cavity QED
Dominik Lentrodt, Kilian P. Heeg, Christoph H. Keitel +1
We develop two ab initio quantum approaches to thin-film x-ray cavity quantum electrodynamics with spectrally narrow x-ray resonances, such as those provided by Mössbauer nuclei. T…
Inducing and detecting collective population inversions of Mössbauer nuclei
K. P. Heeg, C. H. Keitel, J. Evers
Up to now, experiments involving Mössbauer nuclei driven by x-rays have been restricted to the low-excitation regime. Here, a setup is proposed which promises significant excitatio…
Collective effects between multiple nuclear ensembles in an x-ray cavity-QED setup
K. P. Heeg, J. Evers
The setting of Moessbauer nuclei embedded in thin-film cavities has facilitated an aspiring platform for x-ray quantum optics as shown in several recent experiments. Here, we gener…
Interferometric phase detection at x-ray energies via Fano resonance control
K. P. Heeg, C. Ott, D. Schumacher +4
Modern x-ray light sources promise access to structure and dynamics of matter in largely unexplored spectral regions. However, the desired information is encoded in the light inten…
Tunable sub-luminal propagation of narrowband x-ray pulses
K. P. Heeg, J. Haber, D. Schumacher +9
Group velocity control is demonstrated for x-ray photons of 14.4 keV energy via a direct measurement of the temporal delay imposed on spectrally narrow x-ray pulses. Sub-luminal li…
