Title: Geometric engineering on flops of length two

Abstract: Type IIA on the conifold is a prototype example for engineering QED with one charged hypermultiplet. In type IIB, a single D3-probe at the singularity sees an abelian quiver gauge theory. The geometry admits a flop of length one. In this talk, we study the next generation of geometric engineering on singular geometries, namely flops of length two such as Laufer’s example, which we affectionately think of as the conifold 2.0. IIA on the latter geometry gives QED with higher charge states. In IIB, even a single D3-probe gives rise to a nonabelian quiver gauge theory. We study this class of geometries explicitly by leveraging their quiver description, showing how to parametrize the exceptional curve, how to see the flop transition, and how to find the noncompact divisors intersecting the curve.
