Seminar：Mass Generation for Dirac Electrons in Grapheme

Abstract

Graphene,  a two-dimensional allotrope of carbon, has drawn much attention since  its first experimental isolation. Much of this fascination stems from  its exotic low-energy dynamics that is governed by the “Dirac equation”,  a quantum mechanical law of motion that was originally discovered for  relativistic particles such as neutrinos. Unlike for real neutrinos,  however, the Dirac equation for electrons in graphene is generically  massless. In this talk I will discuss how a mass term can be induced in  the material and what the consequences of such mass are. Unlike the  situation for real, relativistic particles, the mass for the charge  carriers in graphene can be space-dependent. I will discuss the  manifestations of this exotic property for the electrical  characteristics of the material.

Biography

In  2003 Markus Kindermann received a PhD in Physics from the University of  Leiden. For three years he then did postdoctoral research at the  Massachusetts Institute of Technology and at Cornell University before  joining in 2006 the School of Physics of the Georgia Institute of  Technology. There he is an associate professor and he does research in  the area of condensed matter theory with a focus on the physics of  electronic nanostructures and quantum information science.
