Control Strategies for Maintaining Transport Symmetries Far From Equilibrium

We present two strategies for controlling the transport dynamics of mesoscopic devices. In both cases, we manipulate the system’s output - such as particle currents and energy flows - while maintaining symmetric transport properties, even under far-from-equilibrium conditions. We provide exact descriptions of each scheme and investigate their characteristics. Notably, one of them minimizes the dissimilarity between the original and modified processes, as quantified by the Kullback-Leibler divergence. These findings can be used to improve the design and control of mesoscopic systems.
