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

Disorder and interaction effects in two-dimensional graphene sheets
TL;DR: In this paper, the interplay between different types of disorder and electron-electron interactions in graphene planes is studied by means of renormalization group techniques, and the low-temperature properties of the system are determined by fixed points where the strength of the interactions remains finite, as in one-dimensional Luttinger liquids.

Coulomb impurity in graphene
TL;DR: In this paper, the problem of screening an electrically charged impurity in a clean graphene sheet was considered, and it was shown that when electron-electron interactions are neglected, the screening charge has a sign opposite to that of the impurity.
