A perturbative CFT dual for pure NS–NS AdS3 strings

L Eberhardt - Journal of Physics A: Mathematical and Theoretical, 2022 - iopscience.iop.org
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 …

Strings in and the WZW model. III. Correlation functions

J Maldacena, H Ooguri - Physical Review D, 2002 - APS
We consider correlation functions for string theory on AdS 3. We analyze their singularities
and we provide a physical interpretation for them. We explain which worldsheet correlation …

BPS correlators for AdS3/CFT2

MR Gaberdiel, B Nairz - Journal of High Energy Physics, 2022 - Springer
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) …

String correlators on AdS3: three-point functions

A Dei, L Eberhardt - Journal of High Energy Physics, 2021 - Springer
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 …

String correlators on AdS3: four-point functions

A Dei, L Eberhardt - Journal of High Energy Physics, 2021 - Springer
A bstract We propose a closed-form formula for genus 0 four-point functions in AdS 3 string
theory with pure NS-NS flux including arbitrary amounts of spectral flow. Our formula passes …

Solving AdS3 string theory at minimal tension: tree-level correlators

A Dei, B Knighton, K Naderi - Journal of High Energy Physics, 2024 - Springer
A bstract We revisit the minimal tension (k= 1) string theory on AdS 3× S 3× 𝕋 4. We propose
a new free-field description of the worldsheet theory and show how localization of string …

Spectral flow and localisation in AdS3 string theory

B Knighton, S Seet, V Sriprachyakul - Journal of High Energy Physics, 2024 - Springer
A bstract We study string theory in three-dimensional Anti-de Sitter spacetime in the path
integral formalism. We derive expressions for generic spectrally-flowed near-boundary …

Non-compact string backgrounds and non-rational CFT

V Schomerus - Physics reports, 2006 - Elsevier
This is an introduction to the microscopic techniques of non-rational bulk and boundary
conformal field theory which are needed to describe strings moving in non-compact curved …

Three-point functions in AdS3/CFT2 holography

A Dei, L Eberhardt, MR Gaberdiel - Journal of High Energy Physics, 2019 - Springer
A bstract Recently, string theory on AdS 3× S 3× 𝕋 4 with one unit of NS-NS flux (k= 1) was
argued to be exactly dual to the symmetric orbifold of 𝕋 4, and in particular, the full …

Spectral flow and string correlators in AdS3× S3× T4

S Iguri, N Kovensky, JH Toro - Journal of High Energy Physics, 2023 - Springer
A bstract We consider three-point correlation functions for superstrings propagating in AdS
3× S 3× T 4. In the RNS formalism, these generically involve correlators with current …
