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. We have shown this for single photon as well as multi-photon photoemission. Based on this property, we aim to perform correlation experiments with electrons, perfectly controlled in 4D. For example, we propose to investigate correlations due to classical Coulomb repulsion, but we also plan to disentangle them from quantum repulsion, i.e., repulsion based on the exchance interaction (Pauli blocking because of the Fermionic character of the electrons). This would represent the Hanbury Brown-Twiss experiment with electrons, here from a single needle tip, which is well known to be a high brightness electron emitter.
