SUMMARY:Coupled spin-1/2 ladders as microscopic models for non-Abelian chir
	al spin liquids
DESCRIPTION:Featuring Po-Hao Huang\, Boston University\n\nPart of the Conde
	nsed Matter Theory Seminar Series.\n\nTopologically ordered states of matte
	r have attracted a much interest in the past decade.  The search for emerge
	nt point-like non-Abelian anyons in two-dimensional electronic system is on
	e of the most exciting problems in condensed matter physics\, since it open
	s many possibilities in quantum computing.  In this talk\, I will construct
	 a two- dimensional lattice model that is argued to realize a chiral spin l
	iquid with Ising topological order.  The logic of the construction is to pr
	epare an array of one-dimensional spin ladders with Ising criticality\, the
	n couple them into the two-dimensional chiral spin liquid with spin-spin in
	teractions that breaks time-reversal symmetry.  This coupled wire construct
	ion takes advantage of describing the one-dimensional spin system by confor
	mal field theory.  I will discuss mainly the theoretical proposal while pro
	vide some numerical evidence to support it.
