We use a quantum master equation to describe transport in double-dot devices. The coherent dot-to-dot coupling affects the noise spectra strongly. For phonon-assisted tunneling, the calculated current spectra are consistent with those of experiments. The model shows that quantum stochastic theory may be applied to some advantage in mesoscopic electronic systems.We use a quantum master equation to describe transport in double-dot devices.
