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.

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: In this paper, lumpy black holes with AdSp x S-q asymptotics are studied, showing the geometry of the horizon near the merger and discussing the correlation between different families of black holes. The presence of non-trivial fluxes in the internal sphere is shown to affect the geometry and the behavior of the solutions.

Summary: We classify the necessary and sufficient conditions to obtain the near-horizon geometry of extremal supersymmetric rotating black holes embedded in 11d supergravity associated to rotating M2-branes. The conditions for supersymmetry are rewritten in terms of differential equations on an eight-dimensional balanced space using G-structure techniques. The geometry is constrained by a master equation reminiscent of the non-rotating case, and the asymptotically AdS(4) electrically charged Kerr-Newman black hole in 4d N = 2 supergravity is embedded in the classification. Additionally, the conditions for the near-horizon geometry of rotating black strings in Type IIB are presented using dualities with the 11d setup.

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 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: In this study, we examine the superconformal index of three-dimensional N = 2 supersymmetric field theories computed via localization on S-1 x S-2. We develop a Cardy-like expansion where the ratio of S-1 radius to S-2 radius is very small. We highlight the sub-leading structures in this expansion and their interaction with the large-N limit for U(N) gauge group theories.

Summary: We improve the constructive enumeration method for 1/16-BPS states in maximally supersymmetric Yang-Mills theory in four dimensions, and identify states that are not of multi-graviton form. We find a few such states for the SU(2) gauge group at relatively high energies, resolving a long-standing puzzle. Along the way, we clarify various subtleties in the literature and prove a non-renormalization theorem regarding the exactness of cohomological enumeration in perturbation theory. We also highlight a giant-graviton-like feature in our results and anticipate that a thorough analysis of our data will shed light on the fundamental properties of black hole microstates.

Summary: The large-N asymptotics of the topologically twisted index of N = 4 SU(N) Super-Yang-Mills (SYM) theory on T-2 x S-2 is investigated and interpreted holographically based on the black hole Farey tail. The regularized on-shell actions of a family of 5d extremal solutions uplifted from the 3d black hole Farey tail are computed in a dual N = 2 gauged STU model to compare with a canonical partition function derived from the twisted index in the large-N limit, improving holographic understanding of the twisted index.

Summary: This paper constructs asymptotically flat supersymmetric three-charge microstate solutions that contain shockwaves. The holographically dual states of the D1-D5 CFT are identified and shown to pass a set of tests, including a precision holographic test, with precise agreement between gravity and CFT. These results may be useful for constructing more general families of black hole microstate solutions.

Summary: In this study, we investigate the four-derivative corrections to five-dimensional minimal gauged supergravity and evaluate the on-shell action of the AdS(5) black hole solution with two independent angular momenta and one electric charge. We recast the action in terms of the supersymmetric chemical potentials after imposing supersymmetry and match the result obtained from the dual superconformal index. We use the on-shell action to determine the corrections to the black hole thermodynamics and find a simple expression for the microcanonical entropy in the supersymmetric and extremal case.

Summary: In this paper, we construct AdS(4) x Sigma and AdS(2) x Sigma x Sigma(g) solutions in six-dimensional F(4) gauged supergravity. The first solution realizes a topologically topological twist, while the second class of solutions gives rise to an anti twist. We compute the holographic free energy of the AdS(4) x Sigma solution and find that it matches the entropy computed by extremizing an entropy functional that is constructed by gluing gravitational blocks. For the AdS(2) x Sigma x Sigma(g) solution, we find that the Bekenstein-Hawking entropy is reproduced by extremizing an appropriately defined entropy functional, which leads us to conjecture that this solution is dual to a three-dimensional SCFT on a spindle. A class of the AdS(2) x Sigma x Sigma(g) solutions can be embedded in four-dimensional T-3 gauged supergravity, which is a subtruncation of the six-dimensional theory.

Summary: In this study, we investigate the properties of AdS5 black holes using a recently proposed giant graviton expansion formula for the index of U(N) maximal super-Yang-Mills theory. By performing a saddle point analysis and maximizing the large N entropy at fixed charges and giant graviton numbers nI, we obtain consistent results with the dual black hole entropy in the small black hole limit. We also provide an explanation for the dual black hole entropy at general sizes by assuming a cancellation mechanism for various giant graviton indices.
