SUMMARY:CMT Group Meeting
DESCRIPTION:Featuring Cheng-Wei Liu\, Boston University\n\nPart of the Cond
	ensed Matter Theory Seminar Series.\n\n"Computational study of spin-glass t
	ransitions approached through\nnon-equilibrium quench"\n\n We propose and d
	emonstrate an efficient simulation scheme for studying\nspin-glass transiti
	ons. This method is based on the idea of approaching\nthe transition point 
	through a non-equilibrium quench process\, formally\nknown as Kibble-Zurek 
	mechanism. Recent studies have shown that there\nexists dual scaling behavi
	or as a function of quench velocity. This dual\nscaling behavior allows us 
	to extract transition point\, static critical\nexponents as well as dynamic
	 exponents to good numerical accuracy with an\nefficient computational effo
	rt. We have tested this approach with\nanti-ferromagnetic Ising model on 3-
	regular random graphs in terms of both\nclassical and quantum phase transit
	ions.
