Ultrafast configuration changes and anomalous diffusion of an aromatic adsorbate on rare-gas nanoparticles
Arne Morlok, Philipp Elsässer, Ulrich Bangert +5
Nanoparticles (NPs) exhibit tunable catalytic properties and serve as nanoreactors for controlled multimolecular chemistry. The kinetics and reactivity of such systems are critical…
Size characterization of neutral rare-gas clusters based on time-resolved polarization anisotropy measurements
Arne Morlok, Grzegorz Kowzan, Ulrich Bangert +3
The size determination of neutral clusters is experimentally challenging. In particular, weakly-bound rare-gas clusters tend to fragment upon ionization, resulting in systematic er…
Dissociative Single and Double Ionization of Pyridine
Sitanath Mondal, Brendan Wouterlood, Gustavo A. Garcia +3
Dissociative ionization processes of simple heterocyclic molecules like pyridine are relevant for an understanding of radiation damage processes in biological material that occur n…
Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern
Linos Hecht, Andre Al Haddad, Björn Bastian +47
We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…
Impact of interference between two infrared pulses driving high harmonic generation
Sarang Dev Ganeshamandiram, Jahanzeb Muhammad, Marvin Schmoll +4
Extreme ultraviolet (XUV) interferometry is technically challenging to implement. One approach to generating interference between two XUV pulses relies on driving high-harmonic gen…
Control of molecular rotation in helium nanodroplets with an optical centrifuge
Ian MacPhail-Bartley, Alexander A. Milner, Frank Stienkemeier +1
We experimentally demonstrate that the rotation of molecules embedded in helium nanodroplets can be controlled with an optical centrifuge, allowing for the study of molecular dynam…
