✦ Synopsis

Electron wave interference effects in GaAs /AlGaAs coupled quantum dots have been studied at 30 mK in magnetic fields with different coupling strength between two dots. In a strong coupling regime, the existence of global trajectories which span two dots was suggested, while in a weak coupling regime, the trajectories were found to be limited in each single dot.
