SUMMARY:Higher Rank Quantum Spin Liquids: From Fractons to Emergent Gravity
DESCRIPTION:Featuring Michael Pretko\, MIT\n\nPart of the Condensed Matter 
	Theory Seminar Series.\n\nQuantum spin liquids are well described in the la
	nguage of gauge theory.  To date\, most theoretical effort has focused on t
	he study of models with a familiar vector gauge field.  However\, there exi
	st stable spin liquids with more complicated gauge structure.  In this talk
	\, I will focus on three-dimensional spin liquid phases described by symmet
	ric tensor ("higher spin") gauge fields.  I will show that these models pos
	sess exotic conservation laws which restrict the gauge charges to exist in 
	lower-dimensional subspaces\, as opposed to propagating in three-dimensiona
	l space.  Some charges are even restricted to a zero-dimensional subspace a
	nd are totally immobile\, in a manifestation of the fracton phenomenon.  As
	 a special case\, I will discuss rank 2 symmetric tensor spin liquids\, whi
	ch provide us with toy models for emergent gravity.
