A04 – Spatio-temporal correlations of electrons emitted from femtosecond laserdriven needle sources
Summary
Individual electrons emitted by needle tips can be spatially fully coherent, even if they are emitted with femtosecond laser pulses. Based on this property, we aim to perform correlation experiments with electrons, perfectly controlled in 4D. For example, we expect to demonstrate quantum repulsion in a Hanbury Brown-Twiss experiment with electrons from a single needle tip, and disentangle it from Coulomb repulsion effects. Furthermore, we will investigate spatial correlations of electrons emitted from more than one tip. Here we expect to perform the Hong-Ou-Mandel experiment for free electrons with two tips, and to measure higher order correlations from an emitter array.
