Abstract
In this paper, we study the electronic properties of a concentric triple quantum ring using exact diagonalization technique. The energy spectra and magnetization for a single electron and two electrons, in the presence of an applied magnetic field, are calculated and discussed. It is shown that, for two-interacting electrons, the period of Aharonov-Bohm oscillations decreases to the half of that for non-interacting electrons which shows the fractional Aharonov-Bohm oscillations for interacting electrons. It is found that the spin-singlet state for two electrons is more stable than the spin-triplet states. Also, magnetization effect decreases due to the electronelectron interaction.
