Observation of Hanbury Brown-Twiss Correlations for Free Electrons

Inequalities for electron-field correlation functions

“…As an electron state is antisymmetrical with respect to a permutation of two particles, electrons avoid coming in pairs which results in a reduced shot noise. This phenomenon called antibunching has been observed experimentally only recently [3]. In analogy to the case of photons, antibunching is equivalent to the fact that the probability of detecting two electrons at two detectors shortly after one another is less than the product of probabilities of the two individual detections.…”
