Description
In this talk, based on upcoming work with J. Gomis and S. Kannagi, I will discuss an important class of defects in Cern simons theory that implement charge conjugation symmetry. These are monodromy defects and, although some of their properties have been studied in N=4 SYM, we study them for the first time in the context of CS theory. Their quantum dimensions can be computed exactly as twining characters, and are associated with somewhat exotic affine algebras.
If time permits, I will also discuss how the duality between CS theory on S^3 and the topological A model on the resolved conifold geometry also accommodates for these new observables. Being heavy in the ’t Hooft limit, they provide a very non trivial test of the duality, and correspond to some special orientifold projection on the string side.
