abstract

We present the computation of logarithmic corrections to near-extremal black hole entropy from one-loop Euclidean gravity path integral around the near-horizon geometry. We extract these corrections employing a suitably modified heat kernel method, where the near-extremal near-horizon geometry is treated as a perturbation around the extremal near-horizon geometry. Using this method we compute the logarithmic corrections to non-rotating solutions in four dimensional Einstein-Maxwell and $\mathcal{N} = 2,4,8$ supergravity theories. We also discuss the limit that suitably recovers the extremal black hole results.

Discussion (0). Continue with ORCID to comment.

  1. One-loop corrections to near extremal Kerr thermodynamics from semiclassical Virasoro blocks

    hep-th 2024-12 conditional novelty 7.0 of 10

    Near-extremal Kerr black holes get a universal (s-1/2) log T_H entropy correction from long-lived modes, derived exactly from Virasoro blocks.

  2. Moduli-dependent one-loop entropy of hyperbolic BPS black hole in AdS$_4$

    hep-th 2026-02 conditional novelty 6.0 of 10

    The one-loop logarithmic entropy correction for a hyperbolic BPS black hole in AdS4 depends on the unfixed horizon scalar modulus and acts as a quantum potential that lifts the classical flat direction.

  3. One loop corrections to the thermodynamics of near-extremal Kerr-(A)dS black holes from Heun equation

    hep-th 2025-06 conditional novelty 6.0 of 10

    Cold near-extremal Kerr-de Sitter black holes carry universal log(T) entropy corrections while rotating Nariai geometries do not, as derived from Teukolsky/Heun connection coefficients.

  4. The spectrum of near-BPS Kerr-Newman black holes and the ABJM mass gap

    hep-th 2024-12 conditional novelty 6.0 of 10

    Near-BPS AdS4 Kerr-Newman black holes are described by an SU(1,1|1) super-Schwarzian theory, yielding a predicted mass gap of order N^{-3/2} and a continuous spectrum above it in ABJM.
