The holographic entanglement entropy (HEE) is investigated for a black hole under the minimal geometric deformation (MGD) procedure, created by gravitational decoupling via an anisotropic fluid, in an AdS/CFT on the brane setup. The respective HEE corrections are computed and confronted to the corresponding corrections for both the standard MGD black holes and the Schwarzschild ones.

  1. Coherent quantum hairy black holes from gravitational decoupling: regularity, geodesics, and scalar ringdown

    hep-th 2026-02 conditional novelty 6.0 of 10

    Gaussian-smearing the gravitational-decoupling hairy black hole produces a regular core and modified photon rings, lensing, and a claimed but absent ringdown spectrum.

  2. Regular black holes with Minkowskian cores: causal structure and observational degeneracy

    gr-qc 2026-07 accept novelty 5.0 of 10

    Regular black holes with Minkowskian cores constructed by gravitational decoupling produce shadows and accretion-disk images nearly indistinguishable from Kerr/Schwarzschild despite radically different interiors.

    gr-qc 2026-07 conditional novelty 4.0 of 10

    A new family of regular black holes with Minkowskian cores is built via gravitational decoupling; their shadows and thin-disk images are nearly indistinguishable from Schwarzschild/Kerr, though the weak-energy-conditi...

  5. Regular hairy black holes by gravitational decoupling: Bardeen and Minkowski-core seeds

    gr-qc 2026-05 unverdicted novelty 4.0 of 10

    Two families of regular hairy black holes are built from Bardeen and hollow seeds by gravitational decoupling with exponential deformation, including critical deformation strengths and Kerr-like rotating extensions.

  6. Gravitational decoupling and regular hairy black holes: Geodesic stability, quasinormal modes, and thermodynamic properties

    gr-qc 2025-12 conditional novelty 4.0 of 10

    For the regular hairy black hole metric (29), larger β shrinks the ISCO and photon sphere, reduces QNM damping, and adds a canonical-ensemble stable phase.

  7. Regular hairy black holes through gravitational decoupling method

    gr-qc 2025-10 unverdicted novelty 4.0 of 10

    Regular hairy black holes are built via gravitational decoupling by deforming Minkowski vacuum under weak energy condition and well-defined horizon constraints, recovering standard black hole metrics as limits.
