Nanoscale mapping of ultrafast magnetization dynamics with femtosecond Lorentz microscopy
Nara Rubiano da Silva, Marcel Möller, Armin Feist +3
Novel time-resolved imaging techniques for the investigation of ultrafast nanoscale magnetization dynamics are indispensable for further developments in light-controlled magnetism.…
Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy
Armin Feist, Nara Rubiano da Silva, Wenxi Liang +2
The control of optically driven high-frequency strain waves in nanostructured systems is an essential ingredient for the further development of nanophononics. However, broadly appl…
Continuous-Wave Multiphoton Photoemission from Plasmonic Nanostars
Murat Sivis, Nicolas Pazos-Perez, Renwen Yu +3
Highly nonlinear optical processes, such as multiphoton photoemission, require high intensities, typically achieved with ultrashort laser pulses and, hence, were first observed wit…
Nanoscale Magnetic Imaging using Circularly Polarized High-Harmonic Radiation
Ofer Kfir, Sergey Zayko, Christina Nolte +10
This work demonstrates nanoscale magnetic imaging using bright circularly polarized high-harmonic radiation. We utilize the magneto-optical contrast of worm-like magnetic domains i…
Attosecond Electron Pulse Trains and Quantum State Reconstruction in Ultrafast Transmission Electron Microscopy
Katharina E. Priebe, Christopher Rathje, Sergey V. Yalunin +4
We introduce a framework for the preparation, coherent manipulation and characterization of free-electron quantum states, experimentally demonstrating attosecond pulse trains for e…
Phase-ordering of charge density waves traced by ultrafast low-energy electron diffraction
S. Vogelgesang, G. Storeck, S. Schramm +3
We introduce ultrafast low-energy electron diffraction (ULEED) in backscattering for the study of structural dynamics at surfaces. Using a tip-based source of ultrashort electron p…
