This work presents an experimental verification of a relation derived by Büttiker (Büttiker M., Phys. Rev. Lett., 65 (1990) 2901) on the correlations between noise voltages at different pair of terminals in multiterminal conductors. Measurements were carried out on several nonreciprocal linear networks realized with a 6-terminal quantum Hall effect device with configurable external connections. For all the configurations tested, the predictions of Büttiker’s formula were verified with an uncertainty of a few percent.

Abstract
This work presents an experimental verification of a relation derived by Büttiker (Büttiker M., Phys. Rev. Lett., 65 (1990) 2901) on the correlations between noise voltages at different pair of terminals in multiterminal conductors. Measurements were carried out on several nonreciprocal linear networks realized with a 6-terminal quantum Hall effect device with configurable external connections. For all the configurations tested, the predictions of Büttiker’s formula were verified with an uncertainty of a few percent.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
