SUMMARY:Quantum Criticality and the Phase Diagrams of Strongly Correlated E
	lectron Matter
DESCRIPTION:Featuring Meigan Aronson\, BNL\nHosted by: David Bishop\, David
	 Campbell\nPoster: http://physics.bu.edu/posters/2013_Fall/1105_Aronson.pdf
	\n\nPart of the Physics Department Colloquia Series.\n\nAbstract: How does 
	order emerge from disorder at T=0\, when only quantum fluctuations are pres
	ent? These T=0 phase transitions or `Quantum Critical Points’ are found i
	n virtually every class of correlated electron system\, including cuprates\
	, heavy fermions\, Fe-based pnictides\, and organic conductors\, and their 
	presence fundamentally changes the properties of the underlying metal from 
	which these ordered phases emerge. The critical modes have many responsibil
	ities in quantum critical systems where they lead to the nucleation of nove
	l phases\, provide pairing for unconventional superconductors\, and can eve
	n lead to the destruction of the metallic state via the localization of ele
	ctrons. I will review here the basic experimental signatures of quantum cri
	tical matter\, selected from classes of materials whose underlying physics 
	is very different\, and outline our emerging understanding of their unusual
	 collective instabilities.
