Shot noise spectrum of superradiant entangled excitons
arXiv:cond-mat/0311615 · doi:10.1103/PhysRevB.69.245323
Abstract
The shot noise produced by tunneling of electrons and holes into a double dot system incorporated inside a p-i-n junction is investigated theoretically. The enhancement of the shot noise is shown to originate from the entangled electron-hole pair created by superradiance. The analogy to the superconducting cooper pair box is pointed out. A series of Zeno-like measurements is shown to destroy the entanglement, except for the case of maximum entanglement.
