SUMMARY:Gauge theory for the cuprates near optimal doping
DESCRIPTION:Featuring Harley Scammell\, Harvard University\nHosted by: Juli
	an Ingham\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n\nWe 
	describe a 2+1 dimensional SU(2) gauge theory for the hole-doped cuprates. 
	The gauge theory emerges upon fractionalization of the fluctuating incommen
	surate spin density waves. Our primary assumption is that all low energy fe
	rmionic excitations are gauge neutral and electron-like\, while the spin de
	nsity wave order is fractionalized into Higgs fields transforming as adjoin
	ts of the gauge SU(2). Under this assumption\, we argue that the SU(2) adjo
	int Higgs theory is sufficiently rich to account for many key properties of
	 the cuprates observed experimentally. In particular\, this talk will focus
	 on the elusive psuedogap phase and offer a description in terms of deconfi
	ned gauge theory.
