The fuzzball proposal states that associated with a black hole of entropy S, there are
expShorizon-free non-singular solutions that asymptotically look like the black hole but …

We review the recent progress towards applying worldsheet integrability techniques to the
${\rm Ad}{{{\rm S}} _ {3}}/{\rm CF}{{{\rm T}} _ {2}} $ correspondence to find its all-loop S matrix …

We construct a conformal field theory dual to string theory on AdS 3 with pure NS–NS flux. It
is given by a symmetric orbifold of a linear dilaton theory deformed by a marginal operator …

A bstract We study superstring theory in three dimensional Anti-de Sitter spacetime with NS-
NS flux, focusing on the case where the radius of curvature is equal to the string length. This …

A bstract A solvable irrelevant deformation of AdS 3/CFT 2 correspondence leading to a
theory with Hagedorn spectrum at high energy has been recently proposed. It consists of a …

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 study the relationship between TsT transformations, marginal deformations of
string theory on AdS 3 backgrounds, and irrelevant deformations of 2d CFTs. We show that …

A bstract The CFT dual of string theory on AdS 3× S 3× S 3× S 1 is conjectured to be the
symmetric orbifold of the\({\mathcal {S}} _ {\kappa}\) theory, provided that one of the two Q±5 …

A bstract In this note we prove a non-renormalization theorem for the 3-point functions of 1/2
BPS primaries in the four-dimensional\(\mathcal {N}= 4\) SYM and chiral primaries in two …

A bstract We revisit the computation of string worldsheet correlators on Euclidean AdS 3 with
pure NS-NS background. We compute correlation functions with insertions of spectrally …
