Deriving the long-string CFT in AdS $_{3}$

Bob Knighton

We revisit the path integral formulation of bosonic string theory in locally-AdS $_{3}$ spacetimes. Through a careful analysis of the worldsheet sigma model, we write down an effectiv…

Tensionless AdS $_{3}$ /CFT $_{2}$ and Single Trace $T T$

Andrea Dei, Bob Knighton, Kiarash Naderi +1

One of the few cases of AdS/CFT where both sides of the duality are under good control relates tensionless $k = 1$ strings on AdS $_{3}$ to a two-dimensional symmetric product CFT. Buil…

Topological defects and tensionless holography

Bob Knighton, Vit Sriprachyakul, Jakub Vošmera

We study topological defect lines in the symmetric-product orbifolds $Sym^{N} (X)$ for a generic seed CFT $X$ . We focus on the defects which preserve the maximum of the $S_{N}$ …

A note on background independence in $AdS_{3}$ string theory

Bob Knighton

In this note, we comment on the path integral formulation of string theory on $M \times S^{3} \times T^{4}$ where $M$ is any hyperbolic 3-manifold. In t…

Unravelling AdS $_{3}$ /CFT $_{2}$ near the boundary

Bob Knighton, Vit Sriprachyakul

We study correlation functions of spectrally-flowed vertex operators in bosonic string theory on $AdS_{3} \times X$ in the path integral formalism. By restricting the path inte…

Exact approaches on the string worldsheet

Saskia Demulder, Sibylle Driezen, Bob Knighton +5

We review different exact approaches to string theory. In the context of the Green-Schwarz superstring, we discuss the action in curved backgrounds and its supercoset formulation,…

Solving AdS $_{3}$ string theory at minimal tension: tree-level correlators

Andrea Dei, Bob Knighton, Kiarash Naderi

We revisit the minimal tension ( $k = 1$ ) string theory on $AdS_{3} \times S^{3} \times T^{4}$ . We propose a new free-field description of the worldsheet theory and show…
