Higher-order renormalization of graphene many-body theory
J. Gonzalez
We study the many-body theory of graphene Dirac quasiparticles interacting via the long-range Coulomb potential, taking as a starting point the ladder approximation to different ve…
Electronic instabilities of a Hubbard model approached as a large array of coupled chains: competition between d-wave superconductivity and pseudogap phase
E. Perfetto, J. Gonzalez
We study the electronic instabilities in a 2D Hubbard model where one of the dimensions has a finite width, so that it can be considered as a large array of coupled chains. The fin…
Electronic instabilities in 3D arrays of small-diameter (3,3) carbon nanotubes
J. Gonzalez, E. Perfetto
We investigate the electronic instabilities of the small-diameter (3,3) carbon nanotubes by studying the low-energy perturbations of the normal Luttinger liquid regime. The bosoniz…
Coulomb screening and electronic instabilities of small-diameter (5,0) nanotubes
J. Gonzalez, E. Perfetto
We investigate the instabilities that may lead to the breakdown of the Luttinger liquid in the small-diameter (5,0) nanotubes, paying attention to the competition between the effec…
Current instability and diamagnetism in small-diameter carbon nanotubes
J. Gonzalez
We investigate the electronic instabilities in carbon nanotubes of short radius, looking for the breakdown of the Luttinger liquid regime from the singular behavior of the charge s…
Insulating, superconducting and large-compressibility phases in nanotube ropes
J. V. Alvarez, J. Gonzalez
The superconducting properties of carbon nanotube ropes are studied using a new computational framework that incorporates the renormalization of intratube interactions and the effe…
