In this work, we investigate the transient quantum transport in a nanoscale Aharonov-Bohm
(AB) 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. By exploring the transient linear conductance and the time evolution of
the reduced density matrix elements of the DQD system, we show the nature of how Fano resonance
is built up in the time domain.
