Luttinger liquid behavior in crossed metal single-wall nanotubes
Résumé
Experimental results for transport through crossed metallic single-wall nanotubes are presented. We observe a zero-bias anomaly in one tube which is supressed by a current flowing through the other nanotube. These results are in agreement with the picture of strongly correlated electrons within the Luttinger liquid model. The most relevant coupling between the nanotubes is the electrostatic interaction generated via crossing-induced backscattering processes.
