Theoretical Physics Seminar: One- and two-point functions in AdS/dCFT

by Prof. De Leeuw (Niels Bohr Institute)

In this talk I will consider N=4 SYM in the presence of a co-dimension 1 defect. This defect CFT is dual to a certain probe D3-D5 brane set-up. I will introduce a framework for quantum computations in this non-trivial dCFT and use it to compute one- and two-point functions. First, I will discuss the one-loop correction to the one-point function of the BPS vacuum state, finding perfect agreement with an earlier string-theory prediction. Second I will discuss two-point functions and their relation to the boundary conformal bootstrap equations and three-point functions in N=4 SYM.
