Out-of-equilibrium charge redistribution in a copper-oxide based superconductor by time-resolved X-ray photoelectron spectroscopy
Denny Puntel, Dmytro Kutnyakhov, Lukas Wenthaus +10
Charge-transfer excitations are of paramount importance for understanding the electronic structure of copper-oxide based high-temperature superconductors. In this study, we investi…
Femtosecond concerted rotation of molecules on a 2D material interface
Kiana Baumgärtner, Misa Nozaki, Marvin Reuner +20
Interfaces between molecules and 2D materials exhibit energy-driven functionalities, wherein charge transfer directs molecular motion. Unlike equilibrium systems, where molecular a…
Tracking the surface atomic motion in a coherent phonon oscillation
Davide Curcio, Klara Volckaert, Dmytro Kutnyakhov +10
X-ray photoelectron diffraction is a powerful tool for determining the structure of clean and adsorbate-covered surfaces. Extending the technique into the ultrafast time domain wil…
Multispectral time-resolved energy-momentum microscopy using high-harmonic extreme ultraviolet radiation
Michael Heber, Nils Wind, Dmytro Kutnyakhov +5
A 790-nm-driven high-harmonic generation source with a repetition rate of 6 kHz is combined with a toroidal-grating monochromator and a high-detection-efficiency photoelectron time…
Ultrafast MHz-rate burst-mode pump-probe laser for the FLASH FEL facility based on nonlinear compression of ps-level pulses from an Yb-amplifier chain
Marcus Seidel, Federico Pressacco, Oender Akcaalan +24
The Free-Electron Laser (FEL) FLASH offers the worldwide still unique capability to study ultrafast processes with high-flux, high-repetition rate XUV and soft X-ray pulses. The va…
Subpicosecond metamagnetic phase transition driven by non-equilibrium electron dynamics
Federico Pressacco, Davide Sangalli, Vojtěch Uhlíř +13
Femtosecond light-induced phase transitions between different macroscopic orders provide the possibility to tune the functional properties of condensed matter on ultrafast timescal…
