Kondo effect in a one-electron double quantum dot: Oscillations of the Kondo current in a weak magnetic field
arXiv:cond-mat/0607044 · doi:10.1103/PhysRevB.74.233301
Abstract
We present transport measurements of the Kondo effect in a double quantum dot charged with only one or two electrons, respectively. For the one electron case we observe a surprising quasi-periodic oscillation of the Kondo conductance as a function of a small perpendicular magnetic field |B| \lesssim 50mT. We discuss possible explanations of this effect and interpret it by means of a fine tuning of the energy mismatch of the single dot levels of the two quantum dots. The observed degree of control implies important consequences for applications in quantum information processing.
