Spin correlation in a double quantum dot-quantum
wire coupled system
IDR
The Kondo effect in one dot is non-locally switched off when the other dot has
an odd number,
N, of electrons and spin 1/2.
Device structure
Possible mechanisms:
l RKKY interaction between the localized
spins
l Modulation of the local density of
states in the wire region by the Fano-Kondo anti resonance
