In this article we consider the second law of black holes (and other causal horizons) in theories where the gravitational action is an arbitrary function of the Lovelock densities. We show that there exists an entropy which increases locally, for linearized perturbations to regular Killing horizons. In addition to a classical increase theorem, we also prove a generalized second law for semiclassical, minimally-coupled matter fields.

Discussion (0). Continue with ORCID to comment.

  1. Gravitational focusing and horizon entropy for higher-spin fields

    gr-qc 2024-12 conditional novelty 7.0 of 10

    Higher-spin fields introduce indefinite terms into the generalized Raychaudhuri equation on Killing horizons, blocking a focusing theorem and a well-defined Wall entropy unless a proposed focusing condition is imposed.

  2. Zeroth law of black hole thermodynamics for higher derivative Proca theories

    The zeroth law of black hole thermodynamics holds to all perturbative orders for higher curvature Einstein-Proca effective field theories.

    gr-qc 2024-11 conditional novelty 6.0 of 10

    In effective field theories of gravity with electromagnetism and scalars, surface gravity and electric potential are constant on black hole horizons up to the accuracy of the EFT, and a modified entropy satisfies the ...

    For small perturbations, the dynamical entropy S_dyn and Wall's entropy S_Wall satisfy S_dyn = (1-v∂_v)S_Wall, and this paper gives a local algorithm that reconstructs S_Wall from S_dyn once a bifurcation-surface cond...

    A Noether-charge derivation of the known HWZ dynamical entropy for generic null surfaces, whose local second-law proof is invalid as printed because Eq. (19) has the wrong sign in K.
