Interplay between Kondo and inter-dot magnetic correlation in coupled quantum dots
The competition between the Kondo effect and the antiferromagnetic interaction is studied in an asymmetric coupled-dot system as a function of the inter-dot coupling. A numerical result for the transport properties at zero temperature is obtained by diagonalizing a cluster, composed by the double-do...
