We investigate the hypothesis that the higher-derivative corrections always make extremal non-supersymmetric black holes lighter than the classical bound and self-repulsive. This hypothesis was recently formulated in the context of the so-called swampland program. One of our examples involves an extremal heterotic black hole in four dimensions. We also calculate the effect of general four-derivative terms in Maxwell-Einstein theories in D dimensions. The results are consistent with the conjecture.

  1. Higher-Derivative Corrections to Reissner--Nordstr\"om Black Holes from Worldline QFT

    hep-th 2026-05 unverdicted novelty 6.0 of 10

    RF² corrections to RN black holes are computed via worldline QFT, verified exactly in G, and shown to require the weak gravity conjecture for non-negative extremal temperature.

  2. A Thermodynamic Positivity Bound on Higher-Derivative 3-Form Couplings in de Sitter, and its Inflationary Consequences

    gr-qc 2025-06 conditional novelty 6.0 of 10

    Thermodynamic positivity of black hole entropy yields a new constraint on higher-derivative 3-form couplings, which in turn restricts viable 3-form inflation models.

  3. Causality Constraints on Black Hole Thermodynamics in Nonlinear Electrodynamics

    hep-th 2025-05 conditional novelty 6.0 of 10

    Causality in nonlinear electrodynamics forces the entropy-to-mass-squared ratio of black holes to decrease with mass and the extremal mass-to-charge ratio to increase with charge.
