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 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 …

A bstract The worldsheet S matrix of strings on the AdS 3× S 3× T 4 background is almost
entirely fixed by symmetries, up to five functions—the dressing factors. These must satisfy …

In these notes we review the S-matrix theory in (1+ 1)-dimensional integrable models,
focusing mainly on the relativistic case. Once the main definitions and physical properties …

A bstract We consider superstrings on the pure-Ramond-Ramond AdS 3× S 3× T 4
background. Using the recently-proposed dressing factors for the worldsheet S matrix, we …

A bstract We propose a procedure to derive quantum spectral curves of AdS/CFT type by
requiring that a specially designed analytic continuation around the branch point results in …

Despite impressive advances in the AdS 3/CFT 2 correspondence, the setup involving
Ramond-Ramond backgrounds, which is related to the D1–D5 system of branes, remained …

We determine the off-shell symmetry algebra and representations of Type IIB superstring
theory on AdS 3× S 3× T 4 with mixed R–R and NS–NS three-form flux. We use these to …

A bstract Building on [31] we investigate the integrable structure of the Wess-Zumino-Witten
(WZW) model describing closed strings on AdS 3× S 3× T 4. Using the recently-proposed …

A bstract We use the lightcone AdS 3× S 3× T 4 superstring sigma model with fermions and
bosons subject to twisted boundary conditions to find the ground state energy in the semi …
