Aspects of many-body physics in graphene

This event is part of the Condensed Matter Theory Seminar Series.

Abstract:
Graphene, due to the Dirac nature of its low-energy quasiparticle, exhibits a host of unconventional
electronic properties. In this talk, I would concentrate on two of these, namely, physics of i) superconducting junctions and ii) magnetic impurities in graphene. I would discuss the unconventional nature of the physics involved for both the cases and show that the helicity of the gapless low-energy Dirac-like quasiparticles in graphene is at the heart of this such unconventional
behavior.
