D-branes in ${\mathrm{AdS}}_3\times {\mathrm{S}}^3\times {\mathbb{T}}^4$ at $k=1$ and their holographic duals

Matthias R. Gaberdiel, Bob Knighton, Jakub Vošmera

String theory on ${\text{AdS}}_3\times {\text{S}}^3\times {\mathbb{T}}^4$ with minimal $k=1$ NS-NS flux can be described in terms of a free field worldsheet theory in the hybrid formalis…
