New trends for the Kondo effect in nanostructures
The Kondo effect in confined nanostructures (quantum dots) provides a testbed for a variety of physical behaviours involving strong electronic correlations. Here some extensions of the Kondo effect beyond the standard single-impurity Anderson model are reviewed. Apart from their fundamental interest, these issues may also open new roads for low-temperature spintronics.
