Abstract content

Two-dimensional gauged linear sigma models with N=(2,2) supersymmetry are a powerful tool for studying the worldsheet theories of type II string compactifications. We construct a certain class of non-Abelian gauged linear sigma models that exhibit an interesting phase structure emerging from non-Abelian strong coupling dynamics. The observed phase structure leads to a duality proposal amongst these models, for which we provide further evidence by matching the respective two sphere partition functions. As some of the models at low energies flow to non-linear sigma models with Calabi-Yau target spaces, the duality proposal results in a correspondence of non-complete intersection Calabi-Yau varieties.
