Title: 
A pair of nonbirational but derived equivalent CalabiYau manifolds from nonAbelian gauge theories 
Abstract: 
We construct a family of (2,2) supersymmetric gauge theories in 2dimensions that flows to a family of (2,2) superconformal fields theories with \hat{c}=3.
The family has two limits and three singular points. The two limits correspond to two CalabiYau manifolds which are not birationally equivalent.
The two are, however, derived equivalent by general principle of supersymmetric quantum field theory.
