SUMMARY:What a Particle Physicist Can Learn from Graphene
DESCRIPTION:Featuring Gordon Semenoff\, University of British Columbia\, Ca
	nada\nHosted by: So-Young Pi\nPoster: http://physics.bu.edu/posters/2012_Sp
	ring/07_Semenoff.pdf\n\nPart of the Physics Department Colloquia Series.\n\
	nAbstract: Graphene is a two-dimensional semi-metal where the electron obey
	s an emergent relativistic Dirac equation. The resulting electronic propert
	ies of this material make it both a fascinating case study in condensed mat
	ter physics and a promising new substance for electronics technology. It al
	so offers a novel testing ground for issues associated with the quantizatio
	n of the relativistic particle\, such as Zitterbewegung and the Schwinger a
	nd Klein effects which have proven difficult to test in the particle physic
	s world\, but have profound effects on the physics of graphene. As well\, g
	raphene electrons are putatively strongly correlated and some effects of st
	rong interaction\, such as dynamical symmetry breaking and the fractional q
	uantum Hall effect\, have been observed. This provides both a simple exampl
	e of the symmetry breaking phenomenon as well as posing a puzzle as to why\
	, if interactions are strong\, so much of the physics of graphene is descri
	bed by weakly interacting\, or even non-interacting electrons. Attempts at 
	some insight into this question will be presented.
