Colloquium: December 11, 2013

ABSTRACT — Graphene, the first and best studied two-dimensional material, has attracted a great deal of attention since its isolation through the “scotch tape” technique at the University of Manchester in 2004 . In this Colloquium I will review a series of outstanding physical properties of graphene, focusing on those that are triggered by the interaction between light and its carriers . More precisely, I will first discuss about the fundamental properties of “Dirac plasmons”  in this material, highlighting the main differences with respect to plasmons in ordinary metals and their potential use in the field of plasmonics . I will then present recent experimental and theoretical results  on the initial stages of the dynamics of hot carriers in graphene, and, in particular, on the controversial issue of “carrier multiplication”.
