SUMMARY:Graphene - relativity at a pencil stroke - Simon Hands (Swansea)
DTSTART:20110302T141500Z

CONTACT:Dr Jock McOrist
DESCRIPTION:I will review some of the recent exciting progress in our know
 ledge of graphene\, a remarkable monolayer allotrope of carbon which promi
 ses to have important technological applications\, with particular focus o
 n its electronic properties. Next I will introduce an effective 2+1d relat
 ivistic field theory description\, taking account of inter-electron intera
 ctions\, and argue that the low-energy behaviour of the charge carriers ma
 y be described by a quantum critical point. I will present results of nume
 rical Monte Carlo simulations to show that the QCP may be relevant for phy
 sical graphene.
