Tracing spatial confinement in semiconductor quantum dots by high-order harmonic generation
H. N. Gopalakrishna, R. Baruah, C. Hünecke +20
We report here on results of experimental-theoretical investigation of high-order harmonic generation (HHG) in layers of CdSe semiconductor quantum dots of different sizes and a re…
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…
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…
Characterization and Application of Hard X-Ray Betatron Radiation Generated by Relativistic Electrons from a Laser-Wakefield Accelerator
Michael Schnell, Alexander Sävert, Ingo Uschmann +3
The necessity for compact table-top x-ray sources with higher brightness, shorter wavelength and shorter pulse duration has led to the development of complementary sources based on…
Crystallographic investigation of Au nanoparticles embedded in a SrTiO thin film for plasmonics applications by means of synchrotron radiation
Davide Pincini, Claudio Mazzoli, Hendrik Bernhardt +4
Self-organized monocrystalline Au nanoparticles with potential applications in plasmonics are grown in a SrTiO matrix by a novel two-step deposition process. The crystalline pr…
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…
Thomson scattering from near-solid density plasmas using soft x-ray free electron lasers
A. Hoell
We propose a collective Thomson scattering experiment at the VUV free electron laser facility at DESY (FLASH) which aims to diagnose warm dense matter at near-solid density. The pl…
