Zusammenfassung: | We investigate the real-time dynamical properties of Rabi-type oscillation through strongly correlated quantum-dot systems by means of accurate hierarchical equations of motion. It is an extension of the hierarchical Liouville-space approach for addressing strongly correlated quantum-dot systems. We study two paradigmatic models, the single quantum-dot system, and serial coupling double quantum-dot system. We calculate accurately the time-dependent occupancy of quantum-dot systems subject to a sudden change of gate voltage. The Rabi-type oscillation of the occupancy and distinct relaxation time of the quantum-dot systems with different factors are described. This is helpful to understand dissipation and decoherence in real-time dynamics through nanodevices and provides a theoretical frame to experimental investigation and manipulation of molecular electronic devices. |
