We use mirror symmetry to determine and sum up a class of membrane instanton corrections to the hypermultiplet moduli space metric arising in Calabi-Yau threefold compactifications of type IIA strings. These corrections are mirror to the D1 and D(-1)-brane instantons on the IIB side and are given explicitly in terms of a single function in projective superspace. The corresponding four-dimensional effective action is completely fixed by the Euler number and the genus zero Gopakumar-Vafa invariants of the mirror Calabi-Yau.

  1. Towards the Non-Perturbative Completion of 4d N=1 Effective Theories of Gravity

    hep-th 2025-10 conditional novelty 7.0 of 10

    Small-volume regimes of flop curves in 4d N=1 F-theory require non-perturbative states—blow-up moduli and D3-string excitations—to complete the locally enhanced N=2 spectrum.

  2. Testing F-theory GUTs with the Axiverse

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    In F-theory GUTs, non-universal ALPs induced by hypercharge flux satisfy g_aγ/m_a well below the QCD axion prediction when gauge couplings unify near the string scale.

  3. Coexisting Flux String Vacua from Numerical K\"ahler Moduli Stabilisation

    hep-th 2025-07 conditional novelty 5.0 of 10

    Numerical scans of Type IIB compactifications find single scalar potentials containing coexisting KKLT/LVS and Kahler-uplifted/LVS minima, including AdS, Minkowski, and dS pairs.
