Abstract

In this work, we revisit and elaborate on twisted holography for AdS$_3 \times S^3 \times X$ with $X= T^4$, K3, with a particular focus on K3. We describe the twist of supergravity, identify the corresponding (generalization of) BCOV theory, and enumerate twisted supergravity states. We use this knowledge, and the technique of Koszul duality, to obtain the $N \rightarrow \infty$, or planar, limit of the chiral algebra of the dual CFT. The resulting symmetries are strong enough to fix planar 2 and 3-point functions in the twisted theory or, equivalently, in a 1/4-BPS subsector of the original duality. This technique can in principle be used to compute corrections to the chiral algebra perturbatively in $1/N$.

Author indications on fulfilling journal expectations

  • Provide a novel and synergetic link between different research areas.
  • Open a new pathway in an existing or a new research direction, with clear potential for multi-pronged follow-up work
  • Detail a groundbreaking theoretical/experimental/computational discovery
  • Present a breakthrough on a previously-identified and long-standing research stumbling block

List of changes

We are grateful to the anonymous referee for their report and feedback on the draft.
In view of their comments, we have made the following changes:

1.) A more detailed discussion about the notion of twisting espoused in this paper, particularly twisting supergravity, on page 1.
2.) Added a footnote on page 2 with comments about the case of AdS3xS3XS3xS1.
3.) Corrected the typo pointed out in equation 2.5.11.
4.) Clarified that the appearance of C^{22} comes from H^2(K3), on the same page.

Reports on this Submission

Report #1 by Anonymous (Referee 2) on 2024-9-29 (Invited Report)

Strengths

Twisted holography provides one of the few examples of solvable models of AdS/CFT. This paper makes signifcant advances within this framework.

Weaknesses

The paper is very mathematical and difficult to understand for the general audience.

Report

The paper works out the details of twisted holography for the famous D1D5 system. This is a very important contribution to the field. Twisted holography is one of the few exactly solvable examples of AdS/CFT and it is important to pin down all the details. This may well lead to a better understanding of holography and string theory more generally.

I recommend publication of the article with the minor corrections that the authors have made. As the corrections are minor, my previous evaluation stands.
