Summary: This study explores how the black hole complementarity principle can arise from quantum gravitational dynamics using a local semiclassical approximation. The findings suggest that the decoupling of different degrees of freedom is crucial for replicating infalling information without cloning it. The study also reveals that hair, which retains a residual time-dependent quantum state, can mirror infalling information after a decoupling time.

Summary: This study examines the stability of black hole saddles inside a spherical reflecting cavity, finding that coupled modes can be diagonalized in the Lichnerowicz operator to define a natural generalization of the pure-trace Wick-rotation recipe. This recipe reproduces the expected result from black hole thermodynamics, where large Euclidean black holes are stable saddles while small Euclidean black holes are unstable.

Summary: Researchers calculated the Bekenstein-Hawking entropy of near-extremal AdS(4) electrically charged rotating black holes using three different methods and found a unique and universal expression for the entropy and microstate counting via the AdS/CFT correspondence. They extended the Kerr/CFT correspondence to the near-extremal case, computed the left and right central charges, and utilized hidden conformal symmetry to calculate the Frolov-Thorne temperatures for the near-horizon geometry, providing a microscopic foundation for Hawking radiation.

Summary: The article discusses a new method of bending the BTZ black hole connection on the Bruhat-Tits tree and demonstrates its correlation with CFT at finite temperatures. By specific coordinate transformations, the connection between p-adic BTZ background and Bruhat-Tits tree background is established, revealing non-trivial local Weyl transformations in the CFT.

Summary: This article uses holography to study real-time correlators for N = 4 super Yang Mills fields coupled to a pair of entangled quarks. By considering the acceleration of the two quarks, the connection with the ER=EPR conjecture is made.

Summary: We construct the holographic duals to a large N, strongly coupled N = 4 super Yang-Mills conformal field theory defined on a four-dimensional de Sitter-Schwarzschild background. There are two distinct five-dimensional bulk solutions: the static black tunnel with two disconnected horizons, and the black hammock with one horizon in the bulk. The hammock horizon is not a Killing horizon, possessing interesting properties like non-vanishing expansion and shear, and allowing classical flow along it.

Summary: This study investigates logarithmic corrections to the entropy of supersymmetric, rotating, asymptotically AdS(5) black holes and black strings. It uses the AdS/CFT correspondence to determine the entropy on the field theory side. The results show perfect agreement between gravitational and field-theoretic methods, providing a window into precision microstate counting and demonstrating the efficacy of low-energy, symmetry-based approaches for asymptotically AdS black objects under certain conditions.

Summary: The study investigates the information paradox of eternal black holes with charges in a doubly-holographic model, involving calculating entanglement entropy and proposing two strategies to address the paradox. The research aims to properly describe the black hole information paradox using enough degrees of freedom on the brane in the doubly-holographic setup.

Summary: We study the flows of non-supersymmetric attractor black holes and find two types of extremal black hole solutions with attractor mechanism: one smooth at the horizon and the other non-smooth. The former is thermodynamically unstable, while the latter is stable.

Summary: The connection between quantum information and quantum gravity has attracted the interest of physicists. A new class of gravitational observables has been proposed to explore holographic complexity. This paper investigates the generalized volume-complexity for the Reissner-Nordstrom-AdS black hole in 4 dimensions. The findings suggest a discontinuous variation in bulk physics that represents the complexity of the thermofield double state defined on the boundary.

Summary: By applying the quantum extremal surface construction, we calculated the Page curve for eternal Reissner-Nordstrom black holes, ignoring backreaction and the greybody factor. The inclusion of islands outside the horizon of the black hole results in the entanglement entropy of Hawking radiation reproducing the Bekenstein-Hawking entropy with an additional term representing the effect of matter fields, helping to address the black hole information paradox.

Summary: The study reveals that the radius of the Einstein ring in the lensed response of a charged AdS black hole is independent of the chemical potential, showing behavior similar to weakly interacting quantum systems. Furthermore, the temperature dependence of the radius of such a ring exhibits a distinct feature with a significant increase at low temperatures, while the ring remains unchanged at the edge of the screen for weakly interacting systems. This distinctive feature is attributed to the high energy modes of strongly coupled systems with a gravity dual.

Summary: This study investigates the evaporation rate of spherically symmetric black holes affected by radiation extraction near the horizon, showing that the rate can be altered depending on the placement of an absorptive screen near the horizon. Modifications to the scrambling time defined by Pennington's work are found, with logarithmic corrections dependent on the screen placement. Furthermore, the study suggests that the screen cannot be placed arbitrarily close to the horizon, leading to the conclusion that black hole mining using a screen may not significantly impact the black hole's lifetime.

Summary: This paper extends the study of asymptotic flat black holes by discussing the island rule in vacuum states. The emergence of the island at late times and its boundary's dependence on the position of the cutoff surface are observed, which is different from the case of eternal black holes. Different states have a significant impact on the entropy in the island formula, leading to different results for the Page time.

Summary: The study focuses on two-dimensional eternal black holes with non-zero mass, interacting with a CFT on a circle. By computing the Page curve, it is found that the entropy rises linearly at early times and remains constant at late times, depending on the size of the thermal baths. The critical size and Page time are proportional to the ratio of the central charges of the conformal defect and the bath CFT.
