Structural dynamics probed by high-coherence electron pulses
Armin Feist, Gero Storeck, Sascha Schäfer +1
Ultrafast measurement technology provides essential contributions to our microscopic understanding of the properties and functions of solids and nanostructures. Atomic-scale vistas…
Orbital angular momentum superposition states in transmission electron microscopy and bichromatic multiphoton ionization
K. Eickhoff, C. Rathje, D. Köhnke +5
The coherent control of electron beams and ultrafast electron wave packets dynamics have attracted significant attention in electron microscopy as well as in atomic physics. In ord…
High-purity free-electron momentum states prepared by three-dimensional optical phase modulation
Armin Feist, Sergey V. Yalunin, Sascha Schäfer +1
We demonstrate the quantized transfer of photon energy and transverse momentum to a high-coherence electron beam. In an ultrafast transmission electron microscope, a three-dimensio…
Few-nm tracking of magnetic vortex orbits and their decay with ultrafast Lorentz microscopy
Marcel Möller, John Henri Gaida, Sascha Schäfer +1
Transmission electron microscopy is one of the most powerful techniques to characterize nanoscale magnetic structures. In light of the importance of fast control schemes of magneti…
