Nanoscale Confinement Enhances Ultrafast Demagnetization
Yoav William Windsor, Tobias Lojewski, Moumita Kundu +21
Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…
Disorder-induced localisation in the Mott-Hubbard model
Ričards Kristers Knipšis, Friedemann Queisser, Jesumony Jayabalan +4
For the Fermi-Hubbard model in the Mott insulator phase, we employ the hierarchy of correlations to study how doublon and holon quasi-particle excitations are affected by adding di…
Analysis of long-lived effects in high-repetition-rate stroboscopic transient X-ray absorption experiments on thin films
Tobias Lojewski, Loïc Le Guyader, Naman Agarwal +41
Time-resolved X-ray absorption spectroscopy (tr-XAS) has been shown to be a versatile measurement technique for investigating non-equilibrium dynamics. Novel X-ray free electron la…
Distinct amplitude mode dynamics upon resonant and off-resonant excitation across the charge density wave energy gap in LaTe3 investigated by time- and angle-resolved photoemission spectroscopy
Kecheng Liu, Takeshi Suzuki, Yigui Zhong +8
Non-equilibrium states generated by ultrafast laser pulses are characterized by specific phenomena that are not accessible in static measurements. Previous time- and angle-resolved…
Electron phonon coupling in ultrathin Pb films on Si(111): Where the heck is the energy?
M. Tajik, T. Witte, Ch. Brand +4
In this work, we study the heat transfer from electron to phonon system within a five monolayer thin epitaxial Pb film on Si(111) upon fs-laser excitation. The response of the elec…
Femtosecond spin-state switching dynamics of spin-crossover molecules condensed in thin films
Lea Kämmerer, Gérald Kämmerer, Manuel Gruber +22
The photoinduced switching of Fe(II)-based spin-crossover complexes from singlet to quintet takes place at ultrafast time scales. This a priori spin-forbidden transition triggered…
