The connection between noise and quantum correlations in a double quantum dot
| Type of Publication: | Journal article |
| Author: | Bodoky, Fabian; Belzig, Wolfgang; Bruder, Christoph |
| Year of publication: | 2008 |
| Published in: | Physical Review B ; 77 (2008). - 035302 |
| DOI (citable link): | https://dx.doi.org/10.1103/PhysRevB.77.035302 |
| Summary: |
We investigate the current and noise characteristics of a double quantum dot system. The strong correlations induced by the Coulomb interaction create entangled two-electron states and lead to signatures in the transport properties. We show that the interaction parameter phi, which measures the admixture of the double-occupancy contribution to the singlet state and thus the degree of entanglement, can be directly accessed through the Fano factor of super-Poissonian shot noise.
