Summary: In this study, mass/energy formulas for extended thermodynamics, mixed thermodynamics, and holographic conformal field theory (CFT) thermodynamics are provided for charged and rotating Kerr-Newman Anti-de Sitter black holes. First-order phase transitions and criticality phenomena are observed in the canonical ensemble with fixed angular momentum, volume, and central charge for the CFT thermal states dual to the black hole. The CFT states are found to not be analogous to Van der Waals fluids, despite the critical exponents falling into the universality class predicted by mean field theory. Additionally, (de)confinement phase transitions are examined in the grand canonical ensemble with fixed angular velocity, volume, and central charge of the CFT. It is suggested that near zero temperature (de)confinement phase transitions can occur with the CFT angular velocity solely depending on the CFT volume.

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: A novel structure in Einstein-Maxwell-dilaton gravity is uncovered, featuring an AdS(2) x S-2 solution with independent length scales controlled by dilaton coupling lambda. The perturbation problem for this solution is solved, revealing independently propagating towers of states composed of gravitons, photons, and dilatons, with associated effective potentials. The effective potentials describe modes obeying conformal quantum mechanics and provide crucial data for any future construction of a holographic dual to these AdS(2) x S-2 configurations.

Summary: This research focuses on the analytic continuations of holographic renormalization group (RG) flows beyond their infrared (IR) fixed points, which provide a natural framework for describing physics inside black holes. The study constructs a monotonic holographic a-function for counting degrees of freedom along a trans-IR flow. It is argued that the degrees of freedom become sparse and vanish when reaching a trans-IR endpoint represented by a Kasner singularity. Furthermore, the research demonstrates that entanglement and complexity from volume are generally insufficient in probing the trans-IR flows, while 2-point correlations and complexity from action are complementary and more effective in this regard.

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: 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: 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 article introduces the recasting of Einstein gravity minimally coupled to a scalar field with a two-parameter Higgs-like self-interaction in three spacetime dimensions in terms of a Chern-Simons form. Depending on the sign of the self-interaction couplings, the result can be g(+) circle plus g(-) as so(2, 2), so(3, 1), or iso(2, 1). The field equations can be expressed through the field strength of non-flat composite gauge fields, and conserved charges can be obtained from boundary terms in the action.

Summary: In the study of holographic complexity for rotating black holes within the framework of complexity equals action and complexity equals volume conjectures, a simplification was found in a class of odd-dimensional equal-spinning black holes. A direct connection between complexity of formation and thermodynamic volume for large black holes was uncovered. The rate of growth of complexity was also examined, revealing that it approaches a constant at late times, but Lloyd's bound is generally violated.

Summary: The study investigates the thermodynamic properties of Quantum Extremal Surfaces (QES) in the semi-classical JT gravity, showing that the Wald entropy fully encapsulates the generalized entropy and deriving the first law of nested Rindler wedge thermodynamics. In the microcanonical ensemble, the semi-classical first law implies the QES's generalized entropy is stationary at fixed energy, suggesting an equivalence between the thermodynamics of the nested Rindler wedge and QES.

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 paper, a new approach is developed to reexamine quadratically superintegrable systems on the two-sphere without explicit constraints on representations or realizations. By using polynomials in the enveloping algebra of su(3), a new six-dimensional cubic algebra with integer structure constants is generated, representing the symmetry of these superintegrable systems. This algebraic structure is related to the Racah algebra R(3) and offers insights into the symmetries of such systems.

Summary: The conformal extension of the BMS3 algebra is constructed with nonlinear terms and central extensions determined by the central charge of the Virasoro subalgebra. It can be interpreted as an infinite-dimensional nonlinear extension of the AdS(4) algebra with nontrivial central charges. The Lorentz subalgebra [sl(2, R)] is embedded within the conformal algebra, and the conformal extension of BMS3 can be further regarded as a W-(2,W-2,W-2,W-1) algebra.

Summary: The study demonstrates that the geometrization of the AKNS integrable hierarchy relies on the construction of novel boundary conditions for the gravitational field. These conditions correspond to an infinite set of AKNS commuting conserved charges, with gravitational configurations studied through SL(2, R) conjugacy classes, including conical singularities and black hole solutions.

Summary: The conformal symmetry algebra in 2D is related to its ultra/non-relativistic version without any limiting process through a nonlinear map of the generators. BMS3 generators emerge from the chiral components of the stress-energy tensor for a generic classical CFT2. Supertranslation generators do not span Noetherian symmetries, but BMS3 becomes a symmetry when the CFT2 is marginally deformed by adding a term to the Hamiltonian. The deformation can be described through the original CFT2 on a curved metric, with BMS3 symmetries arising from deformed conformal Killing equations.

Summary: This study constructs and analyzes the moduli space for a classical field theory with complex stable multi-soliton solutions. The researchers show that a one-dimensional moduli space captures the center of mass motion well for the one and two-soliton solutions. They also demonstrate that even time-delay and spatial displacements can be extracted from a moduli space analysis. A two-dimensional moduli space is proposed to describe the newly found triple bouncing scattering in a double peakon scattering.

Summary: Two types of Carrollian field theories can emerge from finite current-current deformations of toroidal CFT2's, with energy and momentum densities fulfilling the BMS3 algebra. When applied to the bosonic string, the electric-like deformation reduces to a tensionless string, while the magnetic-like deformation yields a new theory with an inner Carrollian structure. Classical solutions describe self-interacting null particles moving along null curves of the original background metric.

Summary: The BTZ black hole is part of a family of AdS(3) spacetimes labeled by mass and angular momentum. Naked singularities are mathematically acceptable solutions describing classical spacetimes, with different geodesic behaviors depending on the specific case. The geodesic equations for the entire BTZ family have been integrated, revealing various types of noncircular geodesics, and special attention has been given to circular geodesics with new results.
