SUMMARY:Non-supersymmetric duality from mirror symmetry
DESCRIPTION:Featuring Michael Mulligan\, UC Riverside\n\nPart of the HET Se
	minar Series.\n\nThere has been a flurry of recent progress in expanding th
	e list of conjectured bosonization dualities in 2+1 dimensions. For example
	\, the critical theory of a boson coupled to a SU(N) gauge theory with leve
	l-k Chern-Simons term is thought to be dual to the theory of a fermion that
	 is coupled to a U(k) gauge theory with Chern-Simons term at level N-1/2. I
	nitial evidence and motivation for these dualities have come from the study
	 of such theories at large N and k. In this talk\, I'll show how the simple
	st example of mirror symmetry -- a supersymmetric duality between a free N=
	2 chiral multiplet and N=2 QED3 -- supports the conjectured duals at N=k=1.
	 Upon general perturbation\, I'll argue that mirror symmetry implies dual p
	hase diagrams that contain four massive phases. Equivalence at the interven
	ing critical points yields the non-supersymmertric dualities: a Wilson-Fish
	er boson is dual to both scalar and fermionic QED3\, while a free fermion i
	s dual to scalar QED3. Thus\, mirror symmetry can be viewed as a parent dua
	lity from which these non-supersymmetric dualities descend. In addition\, I
	'll discuss a few applications of these dualities to condensed matter syste
	ms.
