Summary: In this study, the generalized entanglement entropy in the higher-dimensional two-sided eternal black hole is investigated using double holography. By introducing an end of the world ETW brane, a new type of Ryu-Takayanagi surface is discovered alongside the previously known Hartman-Maldacena surface and the island Ryu-Takayanagi surface. The phase transition among the three Ryu-Takayanagi surfaces at different temperatures is explored and the phase diagram as well as the Page curve are obtained.

Summary: Hollands, Kovacs, and Reall have defined dynamical black hole entropy for gravitational effective field theories (EFTs) building upon previous work by Wall. This entropy satisfies the second law of black hole mechanics to quadratic order in perturbations around a stationary black hole. We have determined the explicit form of this entropy for the EFT of 4d vacuum gravity, including terms in the action with up to 6 derivatives. An open question remains regarding the gauge invariance of this black hole entropy definition, which we have shown to hold for the EFT of vacuum gravity with up to 6 derivatives but can fail when 8 derivative terms are included. We have also derived an entropy for Einstein-Gauss-Bonnet theory by treating it as an EFT with vanishing 6 derivative terms.

Summary: This study develops an effective theory in two directions for perturbations around black holes with scalar hair, including transformations of the scalar-Gauss-Bonnet theory and perturbations around an axisymmetric, slowly rotating black hole. By utilizing methods like galileon operators, the effective theory for perturbations efficiently describes and constrains a broad range of scalar-tensor theories.

Summary: We study the dimensional reduction of (3 + 1)-dimensional Einstein gravity with minimally coupled massless scalar matter to (1 + 1)-dimensions, where the matter theory becomes non-minimally coupled with the dilaton. We construct a self-consistent one-loop effective theory for this model and investigate the corresponding quantum extremal islands.

Summary: This article investigates the second law of black hole mechanics in gravitational theories with higher derivative terms. The author describes a method for defining an entropy that satisfies the second law to linear and quadratic orders in perturbations, treating the higher derivative terms as effective field theory. Additionally, the author addresses some outstanding issues with the method, such as gauge invariance and its relation to the Iyer-Wald entropy.

Summary: This paper presents a mechanism for enhancing the power spectrum during inflation, based on the observation that if the quartic coefficient in the dispersion relation is negative, the amplitude of the power spectrum is substantially enhanced. The mechanism must kick in at scales related to the mass of the PBHs one would like to produce, and it can be applied to produce solar mass PBHs or to contribute to the dark matter energy density.

Summary: In this study, rotating black hole solutions in the Randall-Sundrum II (RSII) model are found by numerically solving a three-dimensional PDE problem. The area and equatorial innermost stable orbits of these solutions are computed. The results show that for large black holes compared with the AdS length scale, the black hole behaves as a four-dimensional object approaching the Kerr metric on the brane, while for small black holes, the solution tends to a five-dimensional Myers-Perry black hole with a single nonzero rotation parameter aligned with the brane. This departure from exact four-dimensional gravity in RSII model may lead to different predictions for rotating black holes compared to standard four-dimensional general relativity.

Summary: In this study, the constraints on effective field theories (EFTs) are investigated through the relative entropy between two theories, namely the target theory and the reference theory. By choosing specific reference theories for a given target theory, the non-negativity of the relative entropy is explored. It is found that constraints on EFTs, such as the single massless scalar field with dimension-eight operator and SMEFT dimension-eight bosonic operators, emerge when higher-derivative operators are generated by the interaction between heavy and light fields. Furthermore, new constraints on SMEFT dimension-eight bosonic operators involving SU(N) and SU(n) gauge fields, as well as operator quartics in the Higgs, are derived, which are stronger than traditional considerations of unitarity and causality. Constraints on Einstein-Maxwell theory with higher-derivative operators from the non-negativity of relative entropy are also investigated. These constraints hold under the assumption that perturbative corrections from interactions involving higher-derivative operators of light fields are not dominant in the EFTs. The implications of this study on the weak gravity conjecture and the second law of thermodynamics are also discussed.

Summary: This paper investigates the long-range force between zero-temperature black holes in two-derivative theories of gravity coupled to matter. It is found that the presence of massless scalar fields and four-derivative corrections can break the no-force condition for these black holes. By calculating the higher-derivative corrections to the scalar charges, it is determined that the higher-derivative corrected black holes can be either self-attractive or self-repulsive, depending on the values of the Wilson coefficients and scalar moduli VEVs.

Summary: In this study, we investigate the multipole moments of rotating black holes in a family of higher-derivative extensions of four-dimensional Einstein gravity. We compute the mass and current multipoles and observe intriguing relations between parity-odd and parity-preserving corrections. We also discuss the implications of these corrections for gravitational wave experiments.

Summary: Causality constraints on scalar-tensor theories involving black holes suggest that within the effective field theory regime, the unobservability of time advancement necessitates a cutoff length approximately the size of the inverse Schwarzschild radius of the black holes. For astrophysical black holes detectable by current gravitational wave detectors, this implies a cutoff length on the order of kilometers. Additionally, implications for gravitational wave science are discussed by exploring potential higher-dimensional operators associated with the scale of UV completion.

Summary: This work confirms the vanishing of Love numbers for Kerr black holes under spin-0 and spin-1 perturbations, and the static conservative responses of Kerr black holes to scalar, electromagnetic, and gravitational fields. The dissipative part of response does not vanish even for static perturbations due to frame-dragging.

Summary: This study investigates black strings/funnels and other black hole configurations in AdS that correspond to different phases of the dual CFT in black hole backgrounds, using different approaches at large D. The phase diagram of uniform and non-uniform black strings/funnels is assembled, and their dynamical stability is examined. Flowing horizons are also constructed. Many of the results are available analytically, although some are known only numerically.

Summary: In this work, consistent compactifications of Einstein-Maxwell and Einstein-Maxwell-Lovelock theories are provided on direct product spacetimes, with specific flux distribution of p-forms over the internal manifold. The dynamics of the p-forms are controlled by interactions with curvature tensor and electromagnetic field, leading to the construction of homogenously charged black p-branes in the corresponding compactified theories.
