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…

Quantum tomography of free electrons

Y. Fang, J. Kuttruff, Z. Zhao +3

Determining the quantum state of a given quantum-mechanical system is a fundamental task in physics. Quantum-state tomography has been pivotal for establishing quantum optics [1-4]…

Gouy Phase-Related Effects in the Free-Space Optical Modulation of Free Electrons

Zhexin Zhao, Yiqi Fang, Mevlana Yunus Uludağ +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…
