Exploring the Kondo effect in magnetic molecules and coupled quantum dots

The screening of a local magnetic moment by itinerant electrons in metals creates a highly

correlated Kondo state, where the electronic spin plays a leading role. Coulomb blockaded

quantum dots in semiconductors as well as magnetic adatoms and molecules on metallic

surfaces have given rise to new challenges and resulted in our revisiting issues about spin

correlations in this state. This talk will describe some of the open questions and interesting

Kondo behavior made evident in beautiful STM experiments on surfaces with adsorbed magnetic

molecules [1], and anticipated in asymmetric coupled quantum dots connected to current leads

[2].
