Spatial and energetic correlations of ultrashort two electron pulses
Stefan Meier, Jonas Heimerl, Felix López Hoffmann +3
When two electrons are emitted from a metallic needle tip into a nanometric volume on femtosecond timescales, strong Coulomb correlations arise. While longitudinal correlations, ma…
Gouy Phase-Related Effects in the Free-Space Optical Modulation of Free Electrons
Zhexin Zhao, Yiqi Fang, Mevlana Yunus UludaÄ +1
Modulating the free-electron wave function with light brings new opportunities to create attosecond electron pulse trains, to probe the quantum coherence of systems with significan…
Probing broken time-reversal symmetry with tailored-light photocurrents
Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4
Light-field-driven photocurrents represent a powerful tool for generating photocurrents without external bias in light-matter systems that lack inversion symmetry. While these phot…
Attosecond physics in optical near fields
Jonas Heimerl, Stefan Meier, Anne Herzig +8
Attosecond science, the electron control by the field of ultrashort laser pulses, is maturing into lightfield-driven electronics, called petahertz electronics. Based on optical fie…
