Channel closing in strong-field photoemission from tip arrays
Leon Brückner, Jonas Heimerl, Constantin Nauk +1
Ultrafast photoemission is a promising avenue for the development of petahertz electronics. For such devices, identifying the precise emission mechanism and quantifying the local f…

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…
