SCGP Weekly Talk: Kevin Costello
Time: 1:00 PM - 2:15 PM
Location: SCGP 102
Description: Title:"The higher genus B model and BCOV theory" Abstract: "We will start by reviewing the role of Givental's Fock space formalism in abstract topological field theory, and in the B model. This will serve as a motivation for the introduction of the BCOV quantum field theory on a Calabi-Yau manifold. The last two lectures will describe a class of integrable hierarchies that appear in BCOV theory on the product of a Calabi-Yau manifold with the complex line." Hashtag: #workshop
Topological Phases of Matter: Akos Nagy
Time: 2:30 PM - 3:30 PM
Location: SCGP 313
Description: Title: Majorana spinors and vortices Abstract: Following the works of Jackiw et al. on the plane (complex dimension 1), I will introduce an Abelian gauge theory on odd dimensional Kahler manifolds. Physically, the theory describes the surface excitations of a TI-SC interface. Solutions of the corresponding variational equations are Majorana spinors over Ginzburg–Landau vortices. I will present my results on closed surfaces. The solutions posses an interesting "concentration" property, which is in accordance with the physical expectations. If time permits, I'll talk about some possible applications, and generalizations to higher dimensions.

Topological Phases of Matter: Jonathan Campbell
Time: 2:30 PM - 3:30 PM
Location: SCGP 313
Description: Title: Stable homotopy theoretic computations in condensed matter physics Abstract: In this talk I'll indicate how standard methods from stable homotopy theory can be used to classify invertible field theories and SPTs. I'll briefly discuss the Freed-Hopkins classification scheme and give examples of computations that confirm classifications of certain SPTs in the physics literature, as well as some novel computations.
