New insights into the laser-assisted photoelectric effect from solid-state surfaces
Lukas Wenthaus, Nikolay M. Kabachnik, Mario Borgwardt +12
Photoemission from a solid surface provides a wealth of information about the electronic structure of the surface and its dynamic evolution. Ultrafast pump-probe experiments are pa…
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…
Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO
O. Fedchenko, J. Minar, A. Akashdeep +20
Altermagnets are an emerging third elementary class of magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they pr…
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…
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…
Direct observation of charge separation in an organic light harvesting system by femtosecond time-resolved XPS
Friedrich Roth, Mario Borgwardt, Lukas Wenthaus +8
The ultrafast dynamics of photon-to-charge conversion in an organic light harvesting system is studied by femtosecond time-resolved X-ray photoemission spectroscopy (TR-XPS) at the…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
Towards Time-Resolved Atomic Structure Determination by X-Ray Standing Waves at a Free-Electron Laser
Giuseppe Mercurio, Igor A. Makhotkin, Igor Milov +6
We demonstrate the structural sensitivity and accuracy of the standing wave technique at a high repetition rate free-electron laser, FLASH at DESY in Hamburg, by measuring the phot…
Quantum Imaging with Incoherently Scattered Light from a Free-Electron Laser
Raimund Schneider, Thomas Mehringer, Giuseppe Mercurio +20
The advent of accelerator-driven free-electron lasers (FEL) has opened new avenues for high-resolution structure determination via diffraction methods that go far beyond convention…
