【 摘 要 】

We consider the electronic analog of the quantum optics Hong-Ou-Mandel interferometer in a realistic condensed matter device based on single electron emission in chiral edge states. For electron-electron collisions we show that the measurement of the zero-frequency current correlations at the output of a quantum point contact produces a dip giving precious information on the electronic wave packets and coherence. As a feature truly unique to Fermi statistics and condensed matter, we show that two-particle interferences between electron and hole in the Fermi sea can produce a positive peak in the current correlations, which we study for realistic experimental parameters.
