Coulomb Induced Positive Current-Current Correlations in Normal Conductors

Martin, Andrew M.
Published in Physical Review Letters. 2000, vol. 84, no. 15, p. 3386-3389
Abstract In the white-noise limit current correlations measured at different contacts of a mesoscopic conductor are negative due to the antisymmetry of the wave function (Pauli principle). We show that current fluctuations at capacitive contacts induced via the long range Coulomb interaction as consequence of charge fluctuations in the mesoscopic sample can be {\it positively} correlated. The positive correlations are a consequence of the extension of the wave-functions into areas near both contacts. As an example we investigate in detail a quantum point contact in a high magnetic field under conditions in which transport is along an edge state.
