Melting, bubble-like expansion and explosion of superheated plasmonic nanoparticles
Simon Dold, Thomas Reichenbach, Alessandro Colombo +32
We report on time-resolved coherent diffraction imaging of gas-phase silver nanoparticles, strongly heated via their plasmon resonance. The x-ray diffraction images reveal a broad…
Generation of Large Vortex-Free Superfluid Helium Nanodroplets
Anatoli Ulmer, Andrea Heilrath, Björn Senfftleben +38
Superfluid helium nanodroplets are an ideal environment for the formation of metastable, self-organized dopant nanostructures. However, the presence of vortices often hinders their…
The Scatman: an approximate method for fast wide-angle scattering simulations
Alessandro Colombo, Julian Zimmermann, Bruno Langbehn +8
Single-shot Coherent Diffraction Imaging (CDI) is a powerful approach to characterize the structure and dynamics of isolated nanoscale objects such as single viruses, aerosols, nan…
Ultrafast relaxation of photoexcited superfluid He nanodroplets
M. Mudrich, A. LaForge, F. Stienkemeier +21
The relaxation of photoexcited nanosystems is a fundamental process of light-matter interaction. Depending on the couplings of the internal degrees of freedom, relaxation can be ul…
Coherent diffractive imaging of single helium nanodroplets with a high harmonic generation source
Daniela Rupp, Nils Monserud, Bruno Langbehn +14
Coherent diffractive imaging of individual free nanoparticles has opened novel routes for the in-situ analysis of their transient structural, optical, and electronic properties. So…
Infrared-active phonon modes in monoclinic multiferroic MnWO4
T. Möller, P. Becker, L. Bohaty +2
We report on polarized infrared reflectivity measurements of multiferroic, monoclinic MnWO4 between 10K and 295K. The full dielectric tensor and the frequency dependence of the ori…
Exploring covalently bonded diamondoid particles with valence photoelectron spectroscopy
Tobias Zimmermann, Robert Richter, Andre Knecht +7
We investigated the valence electronic structure of diamondoid particles in the gas phase, utilizing valence photoelectron spectroscopy. The samples were singly or doubly covalentl…
Ionization and expansion dynamics of atomic clusters irradiated with short intense VUV pulses
B. Ziaja, H. Wabnitz, F. Wang +2
Kinetic Boltzmann equations are used to model the ionization and expansion dynamics of xenon clusters irradiated with short intense VUV pulses. This unified model includes predomin…
Collective orbital excitations in orbitally ordered YVO3 and HoVO3
E. Benckiser, R. Rückamp, T. Möller +6
We study orbital excitations in the optical absorption spectra of YVO3 and HoVO3. We focus on an orbital absorption band observed at 0.4 eV for polarization E parallel c. This feat…
