Surface-Sensitive Mapping of Anisotropic Phonon Cascades in T-WTe
Alp Akbiyik, Felix Kurtz, Nandana Veena Uday +3
Understanding how energy flows from photoexcited carriers into the lattice is essential for describing nonequilibrium phenomena in low-symmetry quantum materials. Here, we use ultr…
Coulomb-correlated electron number states in a transmission electron microscope beam
Rudolf Haindl, Armin Feist, Till Domröse +4
We demonstrate the generation of Coulomb-correlated pair, triple and quadruple states of free electrons by femtosecond photoemission from a nanoscale field emitter inside a transmi…
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…
Tailored high-contrast attosecond electron pulses for coherent excitation and scattering
Sergey V. Yalunin, Armin Feist, Claus Ropers
Temporally shaping the density of electron beams using light forms the basis for a wide range of established and emerging technologies, including free-electron lasers and attosecon…
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…
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…
