Coulomb Interaction and Transport in Graphene Structures

We study the interplay of Coulomb interaction and transport in graphene. The impact of the interaction on graphene is analyzed by means of relaxation rates, in the language of an diagramatic perturbation theory, and by means of its kinetics, in the language of the Boltzman equation. The developed machinery is used to describe Coulomb drag properties of double layer graphene structures, matching the experimental observations.
