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: 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: 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: 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: By utilizing the dilatation operator of U(N) N = 4 super Yang-Mills theory, a 2-local Hamiltonian acting on a graph is defined, leading to the study of scrambling and equilibration in large N Yang-Mills theory. The dynamics on a typical graph result in scrambling within a time consistent with the fast scrambling conjecture, while at weak coupling, the system exhibits a notion of equilibration with a relaxation time characterized by t similar to rho lambda with lambda as the 't Hooft coupling.

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: In this study, the subregion complexity of an evaporating black hole in AdS(3) was computed using multi-boundary wormhole models, resulting in the determination of the associated Page curve. The transition of the Page curve was smoothly realized by tracking the change in choice of HRT surfaces with time and plotting the volume over time. The inclusion of the island at Page time led to a discontinuous jump at the Page time, resulting in a phase transition in the volume subregion complexity plots.

Summary: In this study, we explore the symmetry-resolved entanglement entropy in the context of AdS(3)/CFT2 coupled to U(1) Chern-Simons theory. By relating the generating function for the charged moments to the amount of charge in the entangling subregion, we derive that the symmetry-resolved entanglement entropy is determined by the length of the Ryu-Takayanagi geodesic and the Chern-Simons level k. The results are confirmed by calculations in the dual conformal field theory utilizing the u(1)(k) Kac-Moody symmetry.

Summary: This study introduces a generalized entanglement measure in the context of the AdS/CFT correspondence, taking into account entanglement between spatial degrees of freedom and different fields of the boundary theory, as well as accounting for different winding numbers of strings in the bulk geometry. The results show that the entanglement entropy defined in this way corresponds to the length of geodesics with non-zero winding number, which probe the entire bulk geometry.

Summary: In this paper, we study the charged moments in SL(3, M) higher spin holography and compare them with the dual two-dimensional conformal field theory with W-3 symmetry. For the vacuum state and a single entangling interval, we find that the W-3 algebra of the conformal field theory induces an entanglement W-3 algebra acting on the quantum state in the entangling interval. By computing the corresponding connected correlation functions of the modular charge operator up to quartic order in the chemical potential, we evaluate the logarithm of the charged moments perturbatively. Our result matches known results obtained from the charged topological black hole picture in SL(3, M) higher spin gravity.

Summary: In this study, the role of quantum geometry in ideal Chern insulators is analyzed to describe transport in the presence of external magnetic and electric fields. Novel Berry connections and the deformation of quantum geometry are observed, and the conditions for specific algebra realization are discussed. The effect of the new quantum geometry on electrical transport is investigated, with measurable quantum-mechanical corrections in the Hall response.
