Abstract
We present analytical results on the transient current response of noninteracting openelectronic systems under time-dependent external voltages in both linear- andnonlinear-response regimes. The derivations are based on an equation of motion formalismfor the system reduced single-electron density matrix (Zheng et al 2007 Phys.Rev. B 75 195127). Dissipative interactions between the system and leads aretreated by the nonequilibrium Green’s function approach. The linear-responsedynamics is characterized by the analytical admittance spectrum of the opensystem, through which the quantum coherent transport properties are mapped toequivalent classical circuits. The nonlinear-response current spectrum not only resolvesthe intrinsic energetic configuration of the system, but also reflects the uniquedynamical features due to the transient characteristics of the applied voltages.
