Carbon nanotube based junctions

Carbon nanotubes, graphene rolled onto a seamless cylinder, are prototypes of one-dimensional quantum conductors.
Their diameter of a few nanometers and their length up to several micometers makes them interesting for applications. At the same time quantum correlations and electronic interactions constitute a challenge for the theoretical description of their properties.
Along the years we have been focusing on various transport properties of carbon nanotubes, encompassing Fabry-Perot interference, Kondo anomalies and Luttinger liquid physics.
