title: Stochastic resonance in a double quantum dot system.
abstract: Stochastic resonance (SR) is theoretically investigated for a double quantum dot system represented by two discrete levels in respective wells. The system is driven by a periodic signal and a white noise source with variable amplitude, and thus displays an improved output signal-to-noise ratio, a characteristic signature of SR.
