Multiparticle correlations of an oscillating scatterer
Michael V. Moskalets, Μ. Büttiker · Physical Review B · 2006
Using multiparticle distribution functions, we calculate the correlations produced by a periodically driven scatterer in a system of noninteracting electrons at zero temperature. The multiparticle correlations due to a quantum exchange effect are expressed in terms of photon-assisted scattering amplitudes. The results we obtain are valid for slow but arbitrary in strength driving. We show that even for large amplitude pumps the zero-frequency noise power is related to two-particle correlations. In addition to two-particle correlations a large amplitude pump can generate multiparticle correlations.
