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. Howeve…
Vacuum birefringence at x-ray free-electron lasers
Felix Karbstein, Chantal Sundqvist, Kai S. Schulze +3
We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone. We devise an exp…
Revealing charge anisotropies in metal compounds via high-purity x-ray polarimetry
Lena Scherthan, Juliusz A. Wolny, Isabelle Faus +12
Linear polarization analysis of hard x-rays is employed to probe electronic anisotropies in metal-containing complexes with very high selectivity. We use the pronounced linear dich…
Disentangling X-ray dichroism and birefringence via high-purity polarimetry
Annika T. Schmitt, Yves Joly, Kai S. Schulze +11
High-brilliance synchrotron radiation sources have opened new avenues for X-ray polarization analysis that go far beyond conventional polarimetry in the optical domain. With linear…
Wavelength-dispersive spectroscopy in the hard x-ray regime of a heavy highly-charged ion: The 1s Lamb shift in hydrogen-like gold
T. Gassner, M. Trassinelli, R. Heß +40
Accurate spectroscopy of highly charged high-Z ions in a storage ring is demonstrated to be feasible by the use of specially adapted crystal optics. The method has been applied for…
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…
Vacuum-assisted generation and control of atomic coherences at x-ray energies
Kilian P. Heeg, Hans-Christian Wille, Kai Schlage +9
The control of light-matter interaction at the quantum level usually requires coherent laser fields. But already an exchange of virtual photons with the electromagnetic vacuum fiel…
Exotic dense matter states pumped by relativistic laser plasma in the radiation dominant regime
J. Colgan, J. Abdallah, A. Ya. Faenov +18
The properties of high energy density plasma are under increasing scrutiny in recent years due to their importance to our understanding of stellar interiors, the cores of giant pla…
Uniting Bose-Einstein condensates in optical resonators
D. Jaksch, S. A. Gardiner, K. Schulze +2
The relative phase of two initially independent Bose-Einstein condensates can be laser cooled to unite the two condensates by putting them into a ring cavity and coupling them with…
