Abstract
We study transfer of a single-electron through a quantum ring capacitively coupled to the charged quantum dot placed in its center. For this purpose we solve the time-dependent Schrödinger equation for the pair of particles: the electron traveling through the ring and the other carrier confined within the quantum dot. The correlation effects due to the interaction between the charge carriers are described in a numerically exact manner. We find that the amplitude of Aharonov-Bohm oscillations of the transfer probability is significantly affected by the presence of the dot-confined carrier. In particular the Coulomb correlation leads to inelastic scattering. When the inelastic scattering is strong the transmission of electron through the ring is not completely blocked for (n+1/2) magnetic flux quanta. © 2010 The American Physical Society.
