We provide a consistent N=4 Kaluza-Klein truncation of type IIB supergravity on general 5-dimensional squashed Sasaki-Einstein manifolds. Our reduction ansatz keeps all and only the supergravity modes dual to the universal gauge sector of the associated conformal theories, via the gauge/gravity correspondence. The reduced 5-dimensional model displays remarkable features: it includes both zero-modes as well as massive iterations of the Kaluza-Klein operators on the internal manifold; it contains tensor fields dual to vectors charged under a non-abelian gauge group; it has a scalar potential with a non-supersymmetric AdS vacuum in addition to the supersymmetric one.

  1. Non-Abelian Symmetry Operators from Hanging Branes in $AdS_5 \times S^5$

    hep-th 2025-10 conditional novelty 7.0 of 10

    In AdS5×S5, non-Abelian SO(6) symmetry operators are realized by hanging D5-brane–KK-monopole bound states, matching the Gauss-law operators from the low-energy supergravity action.

  2. Minimal $D=4$ truncations of type IIA

    hep-th 2019-08 conditional novelty 7.0 of 10

    Explicit consistent truncations from massive type IIA on S^6 to minimal D=4 N=2 and N=3 gauged supergravities are constructed and verified.

  3. Gravitational index, black hole saddle degeneracy, and one-form symmetry

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    The |G|-fold degeneracy of supersymmetric AdS5 black hole index saddles is fixed by the flux-quantized BF coupling of the bulk one-form symmetry and persists unmodified in the decompactified black-brane limit.

  4. Supergravity flows, wormholes and their pseudo-Hermitian holographic duals

    hep-th 2026-05 unverdicted novelty 6.0 of 10

    Supergravity truncations admit real-metric wormhole solutions via imaginary scalar extensions whose holographic duals are pseudo-Hermitian and PT-symmetric, interpretable as entangled brane states.

  5. Continuous symmetries and charge measurement of boundary operators in holography

    hep-th 2026-02 conditional novelty 6.0 of 10

    Continuous symmetry operators in holography are U-shaped hanging brane bound states (D5-KK in Type IIB, M5-KK in M-theory) whose worldvolume couplings reproduce the Gauss-law symmetry operators and measure charges of ...

  6. How to uplift non-maximal gauged supergravities

    hep-th 2025-10 conditional novelty 6.0 of 10

    An ExFT-based algorithm reduces the uplift problem to a PDE on the base of the internal manifold and classifies the type IIB uplifts of pure SO(4)-gauged N=4 supergravity by two harmonic functions on a Riemann surface.

  7. Consistent truncations and G$_2$-invariant AdS$_4$ solutions of $D=11$ supergravity

    hep-th 2024-12 conditional novelty 6.0 of 10

    Three new G2-invariant AdS4 vacua of eleven-dimensional supergravity are found numerically, together with explicit uplift formulas and evidence that the G2-invariant sector may be complete.
