Stochastic trajectories and excursions in a double quantum dot system
This research uses a stochastic excursion framework to study noise and fluctuations in double quantum dot systems. By breaking down complex trajectories into 'excursions'—defined by transitions between states A and B—the method allows researchers to analyze transport observables like current, activity, and entropy production at the level of individual events. The findings reveal trade-offs between successful and unsuccessful transport events.
