dc.description.abstract | In the original discussion of the Kondo effect, the increase of the resistance in an alloy such as Cu0.998Fe0.002 at low temperature was explained by the antiferromagnetic coupling between a magnetic impurity and the spin of the host's conduction electrons(1). This coupling has since emerged as a very generic property of localized electronic states coupled to a continuum(2-7). Recently, the possibility to design artificial magnetic impurities in nanoscale conductors has opened avenues to the study of this many-body phenomenon in a controlled way and, in particular, in out-of-equilibrium situations(8-10). So far though, measurements have focused on the average current. Current fluctuations ( noise) on the other hand are a sensitive probe that contains detailed information about electronic transport. Here, we report on noise measurements in artificial Kondo impurities realized in carbon-nanotube devices. We find a striking enhancement of the current noise within the Kondo resonance, in contradiction with simple non-interacting theories. Our findings provide a sensitive test bench for one of the most important many-body theories of condensed matter in out-of-equilibrium situations and shed light on the noise properties of highly conductive molecular devices. | - |
