SUMMARY:Using entanglement to solve quantum many particle systems 
DESCRIPTION:Featuring Steven White\, University of California\, Irvine\nHos
	ted by: David Campbell\nPoster: http://physics.bu.edu/internal//files/get/0
	21015-white.pdf\n\nPart of the Physics Department Colloquia Series.\n\nAbst
	ract:\nWhat is entanglement? How does understanding entanglement help us to
	 understand quantum systems with many particles?  Recent progress has shown
	 that ground states of physical systems have much lower entanglement than t
	hey could have.  The low entanglement can then become the basis for control
	led approximations.  The density matrix renormalization  group (DMRG) preda
	ted this progress\, but we now understand that DMRG is the natural and opti
	mal low-entanglement approximation for 1D quantum systems. More generally\,
	 "tensor network states"  have been developed as the natural low entangleme
	nt approximations for higher dimensions.  I will review this new understand
	ing of quantum systems\, and then illustrate the power of these approaches 
	by discussing our recent progress in finding quantum spin liquids as the gr
	ound states of some frustrated magnetic systems.
