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…
Tracking Microhydration of the NaCl Rocksalt Molecule in Helium Nanodroplets by Penning Ionization Electron Spectroscopy
Ltaief Ben Ltaief, Keshav Sishodia, Robert Richter +6
The microhydration of rock salt (NaCl) molecules was investigated using high-resolution Penning ionization electron spectroscopy (PIES) in helium nanodroplets. Although model calcu…
Model-free pattern separation of two-color ultrafast X-ray diffraction
Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ã. Lægdsmand +33
Two-color X-ray imaging with Free Electron Laser pulses offers a powerful approach for probing ultrafast structural dynamics in nanoscale systems, combining (near-)atomic spatial r…
Relaxation dynamics in excited helium nanodroplets probed with high resolution, time-resolved photoelectron spectroscopy
A. C. LaForge, J. D. Asmussen, B. Bastian +18
Superfluid helium nanodroplets are often considered as transparent and chemically inert nanometer-sized cryo-matrices for high-resolution or time-resolved spectroscopy of embedded…
Interatomic Coulombic decay in lithium-doped large helium nanodroplets induced by photoelectron impact excitation
L. Ben Ltaief, K. Sishodia, J. D. Asmussen +5
Irradiation of condensed matter with ionizing radiation generally causes direct photoionization as well as secondary processes that often dominate the ionization dynamics. Here, la…
Strong-field quantum control in the extreme ultraviolet using pulse shaping
Fabian Richter, Ulf Saalmann, Enrico Allaria +40
Tailored light-matter interactions in the strong coupling regime enable the manipulation and control of quantum systems with up to unit efficiency, with applications ranging from q…
