We clarify a number of issues regarding the worldsheet and spacetime descriptions of string propagation on AdS_3. We construct the vertex operators of spacetime current algebra and spacetime (super) Virasoro generators in the full interacting SL(2) WZW theory and study their Ward identities. We also explain the relation between the analysis in this note and some recent work on this subject.

  1. Deformed BTZ Radiance and Single Trace $T\bar{T}$ Holography

    hep-th 2026-06 accept novelty 6.0

    Long-string emission from rotating λ-deformed BTZ black holes forces a unique origin B-field that matches the value needed for the string spectrum to agree with the Z_w sector of single-trace T T-bar deformed orbifold...

  2. $\boldsymbol{T\overline{T}}$ correlators from tensionless strings

    hep-th 2026-06 unverdicted novelty 6.0

    Constructs deformed vertex operators in a topological string description of T T-bar deformed tensionless AdS3/CFT2 and computes their exact tree-level two-point functions.

  3. Non-supersymmetric strings on AdS$_3$: a world-sheet perspective

    hep-th 2025-12 conditional novelty 6.0

    On AdS3×S3×S3×S1, a Wilson-line deformation of the Spin(16)×Spin(16)⋊Z2 heterotic string produces a level-matched tachyon, so the classical moduli space contains unstable regions.

  4. Strings near BTZ black holes: A Carrollian Chronicle

    hep-th 2025-10 unverdicted novelty 6.0

    The paper classifies families of closed bosonic string solutions in the near-horizon non-extremal BTZ spacetime and identifies novel features via string-Carroll expansion.

  5. Deformed BTZ Radiance and Single Trace $T\bar{T}$ Holography

    hep-th 2026-06 unverdicted novelty 5.0

    Generalizes holar wind to lambda-deformed rotating BTZ, finds emission rates set by Delta S_BH and fixes background B-field at origin to match Z_w twisted sector of single-trace TTbar orbifold.

  6. Toward a worldsheet theory of entanglement entropy

    hep-th 2025-11 unverdicted novelty 5.0

    A new action for entanglement entropy in AdS3/CFT2 derives gravity equations, reduces to a string worldsheet, reproduces bit threads, and unifies several quantum gravity conjectures.

  7. Lecture notes on strings in AdS$_3$ from the worldsheet and the AdS$_3$/CFT$_2$ duality

    hep-th 2026-01 unverdicted novelty 2.0

    Lecture notes deliver a self-contained pedagogical overview of worldsheet strings in AdS3 with NSNS flux, summarizing 25 years of results with emphasis on spectrally flowed correlation functions.
