Abstract
Currents and their fluctuations in two capacitively coupled single electron transistors were studied within the sequential tunneling approach. A speci al attention was focused on the effect of the negative differential resista nce, which appears due to the Coulomb interactions of accumulated charges o n both the single electron transistors. In this case large polarization flu ctuations are activated, which results in a significant enhancement of the current shot noise.
