Phases of QCD3 from string theory

A scenario for the phases of vacuum QCD3 has been proposed recently by Komargodski and Seiberg. Three phases occur in this scenario: a phase of bosonization, a phase of spontaneous global symmetry breaking and a phase captured by some IR CFT. I will present a UV embedding of this scenario in a non-supersymmetric brane configuration in string theory where evidence for a non-supersymmetric Seiberg duality can be found. The magnetic dual explains naturally all the proposed phases, in particular, it explains bosonization and symmetry breaking as different patterns of magnetic squark condensation (or in string theory as different patterns of open string tachyon condensation and brane reconnection). It provides also a natural candidate for the IR CFT of the CFT phase.
