Complex non-Markovian effect on time-dependent quantum transport.
Transient electronic dynamics of a single-lead double-quantum-dot system is significantly affected by intrasystem or lead-mediated interdot coupling. Unique occupancy-state transition features are distinguished in the response current spectrum, due to the presence of irreducible frequency-dependent correlation functions. The complex non-Markovian effects are demonstrated numerically by implementing the exact theory, based on the hierarchical equations of motion for the reduced dynamics of quantum transport systems. They are expected to play a prevalent and nontrivial role in the quantum dynamics of realistic nanoelectronic devices.
