Parametric Amplification of a Terahertz Quantum Plasma Wave
Srivats Rajasekaran, Eliza Casandruc, Yannis Laplace +5
Many applications in photonics require all-optical manipulation of plasma waves, which can concentrate electromagnetic energy on sub-wavelength length scales. This is difficult in…
Comparing XMCD and DFT with STM spin excitation spectroscopy for Fe and Co adatoms on CuN/Cu(100)
M. Etzkorn, C. F. Hirjibehedin, A. Lehnert +11
We report on the magnetic properties of Fe and Co adatoms on a CuN/Cu(100)- surface investigated by x-ray magnetic dichroism measurements and density functiona…
Imaging interatomic electron current in crystals with ultrafast resonant x-ray scattering
Daria Popova-Gorelova, Robin Santra
We demonstrate how the technique of ultrafast resonant x-ray scattering can be applied to imaging dynamics of electronic wave packets in crystals. We study scattering patterns from…
Electronic properties of Mn-Phthalocyanine - C bulk heterojunctions: combining photoemission and electron energy-loss spectroscopy
Friedrich Roth, Melanie Herzig, Cosmin Lupulescu +4
The electronic properties of co-evaporated mixtures (blends) of manganese phthalocyanine and the fullerene C (MnPc:C) have been studied as a function of the concentra…
Quantum optimal control of photoelectron spectra and angular distributions
R. Esteban Goetz, Antonia Karamatskou, Robin Santra +1
Photoelectron spectra and photoelectron angular distributions obtained in photoionization reveal important information on e.g. charge transfer or hole coherence in the parent ion.…
Driving Rabi oscillations at the giant dipole resonance in xenon
Stefan Pabst, Daochen Wang, Robin Santra
Free-electron lasers (FELs) produce short and very intense light pulses in the XUV and x-ray regimes. We investigate the possibility to drive Rabi oscillations in xenon with an int…
