Quantum-statistical current correlations in multilead chaotic cavities

Abstract

Quantum mechanics requires that identical particles be treated as indistinguishable. This requirement leads to correlations in the fluctuating properties of a system. Theoretical predictions are made for an experiment on a multilead chaotic quantum dot that can identify exchange effects in electronic current-current correlations. Interestingly, we find that the ensemble-averaged exchange effects are of the order of the channel number, and are insensitive to dephasing.
