Entanglement in a Noninteracting Mesoscopic Structure
Abstract
We study time dependent electron-electron and electron-hole correlations in a mesoscopic device splitting an incident current of free fermions into two spacially separated particle streams. We analyze the appearance of entanglement as manifested through a Bell inequality test and identify its origin as the Fermi statistics forcing the reservoir to inject spin-singlet pairs. The time window over which the Bell inequality is violated is determined in the tunneling limit and for the general situation with arbitrary transparencies.
