Electron transport in graphene:Field theories,symmetries and topologies of disordered 2D Dirac fermions.

 

Charge carriers in graphene have a relativistic (massless Dirac) spectrum, which is responsible for remarkable electronic properties of this material. In this talk, I will first give a brief overview of the experimental results on transport properties of graphene samples. I will then present recent theoretical advances on electron transport in disordered graphene. Our results show that transport properties of the system depend crucially on the character of disorder. A particular emphasis will be put on symmetries and topology of the underlying field theories of disordered Dirac fermions.
