N2 - We theoretically discuss coherent charge transport through an Aharonov-Bohm interferometer formed by a triple quantum dot using the nonequilibrium Green's function method. In particular, we introduce the coherent indirect coupling parameter α, which characterizes the indirect coupling strength via the reservoir between two quantum dots. When α = 0, the period of the Aharonov-Bohm oscillations for the linear conductance is h/e. For α=0, the period of the AB oscillations becomes 3h/e associated with the three small triangular paths of electrons, which are formed by the triple quantum dot and the reservoir.
