Generation of 10-TW Attosecond X-Ray Pulses in a Free Electron Laser
E. A. Schneidmiller, S. Serkez, I. Zagorodnov +35
Attosecond pulses provide direct access to electron dynamics in atoms, molecules, and solids on their natural timescales. While table-top sources have achieved attosecond pulse dur…
Photoinduced enhancement of chemical shift sensitivity to local vibrations
Ana Martínez Gutiérrez, Oliver Alexander, Pablo Estévez Alonso +26
The advent of novel free-electron laser sources enabling time-resolved x-ray photoelectron spectroscopy (tr-XPS) provides a unique opportunity to monitor local chemical environment…
Two-colour coherent control of nuclear and electron dynamics in photoionization of molecular hydrogen with FEL pulses
Fabian Holzmeier, Alberto Gonzalez-Castrillo, Thomas M. Baumann +12
The extension of coherent - control schemes, recently implemented in free-electron lasers (FELs), to molecular systems offers new opportunities to control chemical dynamics…
Probing the structure of cyclic hydrocarbon molecules with X-ray-induced Coulomb explosion imaging
Kurtis D. Borne, Rebecca Boll, Thomas M. Baumann +27
Coulomb explosion imaging (CEI) is a powerful experimental technique that maps a molecule's geometric structure onto the momenta of ionic molecular fragments produced by rapid mult…
Unraveling real-time chemical shifts in the ultrafast regime
Daniel E. Rivas, Lorenzo Paoloni, Rebecca Boll +21
Traditional x-ray photoelectron spectroscopy (XPS) relies upon a direct mapping between the photoelectron binding energies and the local chemical environment, which is well-charact…
Enhanced One-Color-Two-Photon Resonant Ionization in Highly Charged Ions by Fine-Structure Effects
Moto Togawa, Chunhai Lyu, Chintan Shah +25
Ultraintense pulses from X-ray free-electron lasers can drive, within femtoseconds, multiple processes in the inner shells of atoms and molecules in all phases of matter. The ensui…
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…
Model-free pattern separation of two-color ultrafast X-ray diffraction
Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ø. Lægdsmand +28
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…
Wavelength-Dependent Photodissociation of Iodomethylbutane
Valerija Music, Felix Allum, Ludger Inhester +37
Ultrashort XUV pulses of the Free-Electron-LASer in Hamburg (FLASH) were used to investigate laser-induced fragmentation patterns of the prototypical chiral molecule 1-iodo-2-methy…
Transmission spectroscopy of CF molecules in intense x-ray fields
Rui Jin, Adam Fouda, Alexander Magunia +19
The nonlinear interaction of x-rays with matter is at the heart of understanding and controlling ultrafast molecular dynamics from an atom-specific viewpoint, providing new scienti…
Ultrafast Nuclear Dynamics in Double-Core Ionized Water Molecules
Iyas Ismail, Ludger Inhester, Tatiana Marchenko +30
Double-core-hole (DCH) states in isolated water and heavy water molecules, resulting from the sequential absorption of two x-ray photons, have been investigated. A comparison of th…
Multiple-core-hole resonance spectroscopy with ultraintense X-ray pulses
Aljoscha Rörig, Sang-Kil Son, Tommaso Mazza +14
Understanding the interaction of intense, femtosecond X-ray pulses with heavy atoms is crucial for gaining insights into the structure and dynamics of matter. One key aspect of non…
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…
Cudagrind: A Valgrind Extension for CUDA
Thomas M. Baumann, Jose Gracia
Valgrind, and specifically the included tool Memcheck, offers an easy and reliable way for checking the correctness of memory operations in programs. This works in an unintrusive w…
