摘要：
In this paper, we investigate the transient quantum transport in a nanoscale Aharonov-Bohm interferometer consisting of laterally coupled double quantum dots (DQDs) coupled to the source and drain electrodes. The transient linear conductance is derived at arbitrary temperature of the leads. The resulting transient conductance can be divided into three terms contributed from different transport channels. From the transient linear conductance and the reduced density matrix elements of the DQD system, we show the buildup of Fano resonances in the time domain.
