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…

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…
