We study entanglement entropy and the free energy in recently constructed holographic duals for 5d SCFTs in type IIB supergravity. The solutions exhibit mild singularities, which could potentially complicate holographic applications. We use the relation of the entanglement entropy for a spherical entangling surface to the free energy of the field theory on the five sphere as a well-motivated benchmark to assess how problematic the singularities are. The holographic supergravity computations give well-defined results for both quantities and they satisfy the expected relations. This supports the interpretation of the solutions as holographic duals for 5d SCFTs and gives first quantitative indications for the nature of the dual SCFTs.

    hep-th 2019-09 conditional novelty 6.0 of 10

    Wrapped D4-branes in Romans F(4) gauged supergravity are mapped to supersymmetric and non-supersymmetric AdS vacua, with new non-BPS AdS2 solutions whose stability is checked against the Breitenlohner-Freedman bound.

  3. Uplifting supersymmetric $AdS_6$ black holes to type II supergravity

    hep-th 2019-08 conditional novelty 6.0 of 10

    The author uplifts supersymmetric AdS6 black holes from F(4) gauged supergravity into massive type IIA and type IIB supergravity, and verifies an entropy match in the IIA case.
