Roadmap for Quantum Nanophotonics with Free Electrons
F. Javier García de Abajo, Albert Polman, Cruz I. Velasco +44
Over the past century, continuous advancements in electron microscopy have enabled the synthesis, control, and characterization of high-quality free-electron beams. These probes ca…
Femtosecond and attosecond phase-space correlations in few-particle photoelectron pulses
Rudolf Haindl, Valerio Di Giulio, Armin Feist +1
Temporal correlations in pulsed electron beams reflect the microscopic dynamics of emission and interparticle interaction. In femtosecond electron emission from nanoscale field emi…
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…
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…
Ultrafast transmission electron microscopy using a laser-driven field emitter: femtosecond resolution with a high coherence electron beam
Armin Feist, Nora Bach, Nara Rubiano da Silva +12
We present the development of the first ultrafast transmission electron microscope (UTEM) driven by localized photoemission from a field emitter cathode. We describe the implementa…
A light induced metastable magnetic texture uncovered by in-situ Lorentz microscopy
Tim Eggebrecht, Marcel Möller, J. Gregor Gatzmann +7
Magnetic topological defects, including vortices and Skyrmions, can be stabilized as equilibrium structures by tuning intrinsic magnetic interactions and stray field geometries. He…
