The Emergent String Conjecture constrains the possible types of light towers in infinite-distance limits in quantum gravity moduli spaces. In this paper, we use these constraints to restrict the geometry of the scalar charge-to-mass vectors $(-\vec{\nabla}\log m)$ of the light towers and the analogous vector $(-\vec{\nabla}\log\Lambda_{\text{QG}})$ of the species scale. We derive taxonomic rules that these vectors must satisfy in each duality frame. Under certain assumptions, this allows us to classify the ways in which different duality frames can fit together globally in the moduli space in terms of a finite list of polytopes. Many of these polytopes arise in known string theory compactifications, while others suggest either undiscovered corners of the landscape or new swampland constraints.

  1. Integral Scaling for EFT Strings from the Bottom-Up

    hep-th 2026-07 conditional novelty 7.0

    Under brane-taxonomy axioms and an n_e≤7 homogeneity bound, integral scaling with w≤3 is an exhaustive finite consequence for all EFT string candidates in 4d N=1 moduli slices.

  2. EFT (String) Tower Building

    hep-th 2026-07 conditional novelty 7.0

    Assuming the Integral Scaling Relation and the Emergent String Conjecture, the Kähler potential fixes the UV tower spectrum, and every admissible degree-≤7 tower polytope is a slice of the M-theory G2 polytope.

  3. Sharpened Dynamical Cobordism

    hep-th 2026-05 unverdicted novelty 7.0

    Sharpened Dynamical Cobordism ties the allowed range of critical exponent δ to theory structure ξ, flagging obstructions from non-trivial cobordism charges that require new degrees of freedom.

  4. Taxonomy of Instanton Corrections in Infinite Distance Limits

    hep-th 2026-05 unverdicted novelty 7.0

    The Schwinger integral over light towers captures precisely the instantons with actions in the window (Λ_sp/M_light)^{-1} ≤ S_inst ≤ Λ_sp/M_light, as verified in eight- and seven-dimensional toroidal compactifications.

  5. Alice in Warpland: KK modes, Warped Compactifications and the Swampland

    hep-th 2026-03 unverdicted novelty 7.0

    In codimension-one warped compactifications with exponential potentials, the KK mass decay rate λ_KK is reduced by warping but still satisfies the Sharpened Distance Conjecture precisely when the higher-dimensional po...

  6. The CFT Distance Conjecture and Tensionless String Limits in $\mathcal N=2$ Quiver Gauge Theories

    hep-th 2026-01 unverdicted novelty 7.0

    In N=2 SU quiver theories the large-N Hagedorn temperature depends only on quiver length for linear cases and equals that of N=4 SYM for holographic quivers, with a universal lower bound of 1/sqrt(2) on the exponentia...

  7. An M-theory dS maximum from Casimir energies on Riemann-flat manifolds

    hep-th 2025-07 unverdicted novelty 7.0

    Explicit scale-separated dS5 maximum in M-theory on a 6D Riemann-flat manifold with vacuum energy 10^{-8} in Planck units, obtained via Casimir energies and fluxes.

  8. Kaluza-Klein tower thresholds and scheme dependence of the species scale

    hep-th 2026-07 accept novelty 6.5

    Leading KK-tower local corrections to four-derivative gravity are regulator-dependent EFT matching data, while log N terms are universal within proper-time cutoffs, so species-scale definitions match only parametrically.

  9. Moduli-Space Laplacians, Asymptotic Geometry, and the Emergent String Conjecture

    hep-th 2026-07 conditional novelty 6.0

    Under the Emergent String Conjecture, the logarithm of any principal tower mass has a moduli-space Laplacian eigenvalue quantized to N/(D-d) for KK towers and N/2 for string oscillators, equal to the instanton-weighte...

  10. Stochastic Survival near Swampland Boundaries

    hep-th 2026-06 unverdicted novelty 6.0

    A stochastic survival framework maps swampland control data to conditioned drifts for moduli histories near boundaries via the Doob transform, yielding a universal inward wall response near regular hard boundaries.

  11. EFTs with Symmetric Moduli Spaces: the Landscape and the Swampland

    hep-th 2026-05 unverdicted novelty 6.0

    Using weight polytopes of irreducible representations, a finite list of symmetric moduli spaces satisfies the SDC decay rates; most embed from an E8(8) EFT but three cannot be obtained from string or M-theory compacti...

    hep-th 2026-05 unverdicted novelty 6.0

    Proposes a refinement of the Swampland Cobordism Conjecture for Ω1(BG) with duality bundle G, where diverging commutator width of G requires infinitely many duality defects to realize monodromies via gravitational solitons.

  13. Bordisms between 9d type IIB supergravities and commutator widths of duality groups

    hep-th 2026-05 unverdicted novelty 6.0

    Proposes a refinement of the Swampland Cobordism Conjecture for duality groups, arguing that diverging commutator widths necessitate infinitely many duality defects to realize monodromies in 9d supergravity bordisms.

  14. Taxonomy of Instanton Corrections in Infinite Distance Limits

    hep-th 2026-05 unverdicted novelty 6.0

    The Schwinger integral over light towers captures precisely those instantons with actions in the window (Λ_sp/M_light)^{-1} ≤ S_inst ≤ Λ_sp/M_light.

  15. Gravity Decoupling and Axionic Shift Symmetries

    hep-th 2026-05 unverdicted novelty 5.0

    Axionic string tensions define vector fields on moduli space that split into mutually orthogonal subsets with one decoupling from gravity, and their Laplacian relates to divergent moduli space curvature.

  16. Sharpening the Supersymmetric Axion Weak Gravity Conjecture

    hep-th 2026-05 unverdicted novelty 5.0

    The paper verifies the bound fS/|n| ≤ (π/(2 κ_d)) sqrt((d-1)/(d-2)) for axion instantons and sharpens it to fS/|n| ≤ (1/κ_4) sqrt(7/2) for supersymmetric 4d instantons using three approaches in the string landscape.

  17. Moduli Space Quantum Mechanics

    hep-th 2026-03 conditional novelty 5.0

    Moduli-space geometry induces effective potentials that localize excited quantum wavefunctions in the bulk with positive energies, even for classically runaway potentials.

  18. Stochastic Survival near Swampland Boundaries

    hep-th 2026-06 conditional novelty 4.0

    Surviving inflationary histories develop a universal inward drift near any hard swampland boundary — two times the diffusion over the distance to the edge — regardless of the cutoff's microscopic origin.
