Abstract

Low temperature transport measurement has been performed on a double quantum dot-quantum wire coupled device fabricated from a GaAs/AlGaAs heterostructure. Nonlocal control of the Kondo effect in one dot is realized by manipulating the spin state of the other dot. The modulation of the local density of states in the wire region due to the Fano-Kondo antiresonance, and the Ruderman-Kittel-Kasuya-Yoshida (RKKY) exchange interaction are the two possible mechanisms underlying the observed features.
