Kondo effect in a single wall carbon nanotube with pressure inducing pseudogaps

We are interested to study the Kondo effect present in a system with a T-shape ligation between the single-wall carbon nanotube (SWNT) and a magnetic impurity. The system has studied under pressure and it was observed the opening of the gap in the density of states of the zigzag metallic tube. A tight-binding approximation is used to calculate the SWNT Green's functions. Here we study the disappearance of the Kondo peak as the gap opens and its strong influence on the deformation of the conductance curve. The Kondo effect was considered with the atomic approach with $U\rightarrow\infty$ developed previously. Results of the electronic density of states and curves of the conductance are presented.
