       "Fundamental physics with two-dimensional carbon"


Kivonat:
The two-dimensional form of carbon, also known as graphene, has been 
hailed as wonder material promising, and already delivering, many useful 
applications. This is not the only reason, however, why many theoretical 
physicists have been fascinated with this new material over the last ten 
years. The reason is also that the electronic structure of graphene 
provides an unusually simple and affordable playground for studies of some 
of the basic concepts of modern quantum physics. In this lecture I will 
attempt to give an elementary discussion of three of these: 1) 
Mott-insulator (or "Higgs")  quantum phase transition, and the emerging 
relativity, 2) the spontaneous breaking of "chiral" symmetry, and the 
"Dirac masses" of graphene, and 3) the Jackiw-Rebbi zero-modes, 
topological defects, and their (Clifford) algebras.
