Interference and Interactions in Electronic Nanostructures
The interplay between quantum mechanical interference and electron-electron interactions is one of the great themes of condensed matter physics. Recently, this topic has arisen in the context of nanostructures – quantum dots, metallic nanoparticles, carbon nanotubes, single conducting molecules, etc. I will introduce the general issue of interference and interaction in nanostructures, and then illustrate by choosing two topics from among several possible examples: (1) the ground state spin of quantum dots – toward strong interactions, (2) mesoscopic fluctuations of the Kondo effect, (3) coupling between the spatial interference and spin direction in ferromagnetic nanoparticles, and (4) conduction through single organometallic molecules.
