SUMMARY:Topological Quantum Chemistry and The Topological Periodic Table of
	 Materials
DESCRIPTION:Featuring Andrei Bernevig\, Princeton University\nHosted by: Ch
	ristopher Laumann\nPoster: http://physics.bu.edu/internal//files/download/B
	ernevig-poster.pdf\n\nPart of the Physics Department Colloquia Series.\n\nO
	ne newly discovered characterization of insulators\, metals and semimetals 
	is based on their topological properties. Topological insulators do not con
	duct in the bulk but\, unlike their non-Topological counterparts\, exhibit 
	perfect conduction on their surface. Topological metals conduct in the bulk
	\, but\, unlike their non-Topological counterparts cannot be gapped due to 
	a special type of  protection that allows their low energy electrons to exh
	ibit esoteric phenomena such as chiral anomaly or non-local transport. It w
	as initially thought that the materials exhibiting these phenomena are very
	 special and unique amongst all of the 140000 compounds known to humankind.
	 We will present a review of these ideas and properties of topological mate
	rials. We will then show how\, using a new theory called Topological Quantu
	m Chemistry\, we are able to now catalogue all the topological materials th
	at can possibly exist in nature. We then apply our theory to find that more
	 than 23% of all known compounds - including some of the most interesting m
	aterials in nature - are actually topological. We hence live in a topologic
	al world!
