Transport in coupled quantum dots: Kondo effect versus antiferromagnetic correlation
Transport in coupled quantum dots: Kondo effect versus antiferromagnetic correlation
The interplay between the Kondo effect and the inter-dot magnetic interaction in a coupled-dot system is studied. An exact result for the transport properties at zero temperature is obtained by diagonalizing a cluster, composed by the double-dot and its vicinity, which is connected to leads. It is shown that the …
