A bstract It was recently argued that string theory on AdS 3× S 3× 𝕋 4 with one unit (k= 1) of
NS-NS flux is exactly dual to the symmetric orbifold CFT Sym N (𝕋 4). In this paper we show …

A bstract Superstring theory on\({\mathrm {AdS}} _3\times {S}^ 3\times {\mathbb {T}}^ 4\) with
the smallest amount of NS-NS flux (“k= 1”) is shown to be dual to the spacetime CFT given …

We discuss in detail the 1+ 1-dimensional superconformal field theory dual to type II string
theory on AdS 3× S 3× T 4, emphasizing the string theoretic aspects of this duality. For one …

A bstract We continue our study of the worldsheet theory of superstrings on AdS 3× S 3× 𝕋 4
in the tensionless limit [1]. We consider the theory on higher genus surfaces. We give …

We use integrability techniques to compute structure constants in\(\mathcal {N}= 4\) SYM to
leading order at weak coupling and to leading order in the planar expansion. Three closed …

A bstract The BPS correlators of the symmetric product orbifold Sym N (𝕋 4) are reproduced
from the dual worldsheet theory describing strings on AdS 3× S 3× 𝕋 4 with minimal (k= 1) …

A bstract We exploit null vectors of the fractional Virasoro algebra of the symmetric product
orbifold to compute correlation functions of twist fields in the large N limit. This yields a new …

A bstract We analyze how deforming symmetric product orbifolds of two-
dimensional\(\mathcal {N}\)= 2 conformal field theories by an exactly marginal operator lifts …

We develop a diagrammatic language for symmetric product orbifolds of two-dimensional
conformal field theories. Correlation functions of twist operators are written as sums of …

A bstract We consider D1-D5-P states in the untwisted sector of the D1-D5 orbifold CFT
where one copy of the seed CFT has been excited with a left-moving superconformal …
