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…
Relativistic interaction of long-wavelength ultrashort laser pulses with nanowires
Z. Samsonova, S. Höfer, V. Kaymak +11
We report on experimental results in a new regime of a relativistic light-matter interaction employing mid-infrared (3.9-micrometer wavelength) high-intensity femtosecond laser pul…
Generation of keV hot near-solid density plasma states at high contrast laser-matter interaction
O. N. Rosmej, Z. Samsonova, S. Höfer +13
We present experimental evidence of ultra-high energy density plasma states with the keV bulk electron temperatures and near-solid electron densities generated during the interacti…
