Description
Following the recent work of Eberhardt, Gaberdiel and Gopakumar, exact comparison between various quantities living on the two sides of the AdS/CFT correspondence has become a possibility. The goal of this work is to extend the existing holographic dictionary to include some non-perturbative vacua on both sides. We start by constructing various D-branes of the string theory on ${\rm AdS}_3\times {\rm S}^3 \times \mathbb{T}^4$ at $k=1$ units of NS-NS flux and calculate their associated cylinder amplitudes. We observe that these amplitudes match with the cylinder correlators of certain boundary states of the dual CFT, thus suggesting a direct correspondence between these boundary conditions. We also show that the disk amplitudes of these D-branes localise to those points in the worldsheet moduli space where the worldsheet disk holomorphically covers the spacetime disk.
