This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons can be controlled by application of external electric and magnetic fields, or by altering sample geometry and/or topology. The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge (surface) states in graphene depend on the edge termination (zigzag or armchair) and affect the physical properties of nanoribbons. Different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of electron-electron and electron-phonon interactions in single layer and multilayer graphene are also presented.read more

Electron interactions and scaling relations for optical excitations in carbon nanotubes.
Charles L. Kane,Eugene J. Mele +1 more
TL;DR: It is shown that self-energy and excitonic effects in single wall carbon nanotubes can be understood in a theory of large radius tubes derived from the theory of two dimensional graphene where the Coulomb interaction leads to a logarithmic correction to the electronic self- energy and marginal Fermi liquid behavior.

TL;DR: In this paper, the electron-phonon coupling in graphene, in contrast with the nonrelativistic two-dimensional electron gas, leads to shifts in the phonon frequencies that are nontrivial functions of the electronic density.

TL;DR: In this article, the authors analyzed the electronic properties of Aharonov-Bohm rings made of graphene and showed that the combined effect of the ring confinement and applied magnetic flux offers a controllable way to lift the orbital degeneracy originating from the two valleys, even in the absence of intervalley scattering.
