abstract

The KKLT scenario, one of the few ideas to realize dS vacua in string theory, consists of two steps: the first involves the construction of a supersymmetric AdS vacuum with a small negative cosmological constant, and the second involves breaking supersymmetry and uplifting the energy to achieve dS. In this paper we use conventional holography to argue why it is not possible to complete the first step. We obtain this by putting a bound on the central charge of the dual theory which involves branes wrapping special Lagrangian cycles in CY 4-folds. We find that $l_{\rm AdS}^2 \lesssim \chi(CY_4)$. Since $l_{\rm species}^2\gtrsim \chi(CY_4)$ this leads to $l_{\rm AdS}/l_{\rm species}\lesssim 1$ leading at best to a highly curved AdS which is beyond the validity of the EFT.

  1. The Lorentzian Geometry of Tunneling in Global de Sitter at Late Time

    hep-th 2026-07 conditional novelty 7.0 of 10

    A late-time Lorentzian Hamiltonian/WKB calculation of bubble nucleation in de Sitter reproduces the CDL decay exponent for all tunneling types, with gravity-dominated bubbles going on-shell at the parent horizon.

  2. Warped Numerical Calabi-Yau Metrics

    hep-th 2026-07 conditional novelty 7.0 of 10

    First numerical GKP warped Type IIB flux background on a Dwork quintic, giving a 0.5% throat-volume estimate near the conifold and new metric/harmonic-form/warp-factor techniques.

  3. O(16)$\times$O(16) heterotic theory on $AdS_3\times S^3\times T^4$

    hep-th 2025-10 conditional novelty 6.0 of 10

    The one-loop correction to the O(16)×O(16) heterotic vacuum on AdS3×S3×T4 raises the cosmological constant but never uplifts it to de Sitter for any flux integers, and the Kaluza-Klein modes of the six-dimensional fie...

  4. Backtracking AdS flux vacua

    hep-th 2025-06 conditional novelty 6.0 of 10

    Flux backtracking produces candidate brane-probe singularities for AdS flux vacua, including a new strongly coupled massive IIA singularity conjectured to be the brane picture of DGKT.
