Tunable non-local coupling between Kondo impurities
We study the tuning mechanisms of Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange interaction between two lateral quantum dots in the Kondo regime. At zero magnetic eld we observe the expected splitting of the Kondo resonance and estimate the non-local coupling strength as a function of the asymmetry between the two Kondo temperatures. At nite magnetic elds a chiral coupling between the quantum dots is observed in the Kondo chessboard and we probe
