A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
Electronic and structural fingerprints of charge density wave excitations in extreme ultraviolet transient absorption spectroscopy
Tobias Heinrich, Hung-Tzu Chang, Sergey Zayko +3
Femtosecond core-level transient absorption spectroscopy is utilized to investigate photoinduced dynamics of the charge density wave in 1T-TiSe2 at the Ti M2,3 edge (30-50 eV). Pho…
Light-induced hexatic state in a layered quantum material
Till Domröse, Thomas Danz, Sophie F. Schaible +3
The tunability of materials properties by light promises a wealth of future applications in energy conversion and information technology. Strongly correlated materials such as tran…
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…
