Abstract

Correlations between electrons are at the core of numerous phenomena in atomic, molecular, and solid-state systems. Harnessing free-particle correlations remains challenging, with the recent implementation of nanoscale single-electron sources [1] and observation of weak anti-bunching in electron beams [2, 3]. A powerful approach to induce strong electron-electron interactions is femtosecond-triggered photoemission from nanotips [4, 5] with high spatial and temporal confinement. However, ensemble-averaged detection typically conceals few-body effects.
