Summary: This paper analyzes interesting features of the thermodynamics of the rotating BTZ black hole from the Caratheodory axiomatic postulate, explores adiabatic transformations, and discusses the implications for the second and third laws of black hole thermodynamics, specifically studying the merging of two extremal black holes in detail.

Summary: This study investigates the impact of Horndeski gravity on the AdS/BCFT correspondence, analyzing the 3D black hole corresponding to 2D BCFT, studying the changes in boundary entropy and thermodynamic properties, and indicating a restoration of conformal symmetry. The research also includes a study on the influence of Horndeski gravity on the Hawking-Page phase transition, revealing stable and unstable phases in the plane of free energy versus temperature.

Summary: In this study, the holographic covariant entanglement entropy in a double Wick rotated version of a rotating Banados-Teitelboim-Zanelli black hole (3-dimensional Kerr-AdS solution) is analyzed, where the periodicity of Euclidean time and spatial direction are altered. The dual field theory exhibits negative energy in the Lorentzian signature. The holographic entanglement entropy matches its conformal field theory counterpart, which is derived through a conformal transformation of the correlation functions of twisted operators.

Summary: Noncommutative geometry is a potential candidate for incorporating quantum phenomena into gravitation. The formalism of Hopf algebras and its connection to the algebra of infinitesimal diffeomorphisms are outlined. Spacetime symmetries, vector fields, and differential forms are deformed using a Drinfeld twist, leading to a formulation of noncommutative Einstein equations. The entropy of a noncommutative charged BTZ black hole is obtained using the brick-wall method, and the spectrum and density of states of a charged scalar field are obtained via WKB approximation.

Summary: This article examines an axially symmetric rotating BTZ black hole to understand its interior information. The maximum space-like hyper-surface is used to estimate the time-dependent interior volume, and it is found that the quantum mode entropy of the associated scalar field increases with Eddington time. An evolution relation between the variation of quantum mode entropy and Bekenstein-Hawking entropy is obtained for infinitesimal time intervals, with the characteristic feature being its divergent nature.

Summary: The study expands the bulk reconstruction program by obtaining the boundary representation for a scalar field in a rotating BTZ black hole, revealing novel features near the inner horizon. The representation for fields inside the horizon is also obtained as operators in a single boundary CFT using mirror operator construction.

Summary: In this study, we present an analog model for the Banados, Teitelboim, Zanelli (BTZ) black hole based on a hydrodynamical flow. We numerically solve the fully nonlinear hydrodynamic equations of motion and observe the excitation and decay of the analog BTZ quasinormal modes in the process. We consider both a small perturbation in the steady state configuration of the fluid and a large perturbation, which can be regarded as an example of the formation of the analog (acoustic) BTZ black hole.

Summary: In this study, the effects of the anti-Hawking effect on an Unruh-DeWitt detector orbiting a Banados-Teitelboim-Zanelli black hole in the corotating frame were investigated. It was found that rotation can significantly amplify the weak anti-Hawking effect and either amplify or reduce the strong anti-Hawking effect depending on boundary conditions. A nonmonotonic relationship between angular momentum and detector temperature was observed for the strong anti-Hawking effect. Furthermore, it was noted that the weak anti-Hawking effect is independent of a changing AdS length, while a longer AdS length increases the temperature range of the strong anti-Hawking effect.

Summary: In this study, an exact rotating BTZ-like black hole solution is obtained by solving the gravitational field equations and bumblebee motion equations. The Lorentz symmetry is violated only in the radial direction and requires a linear functional potential for the bumblebee field. The black hole has two horizons and an ergosphere, which depend on the bumblebee coupling constant. The entropy-area relation, first law of thermodynamics, and Smarr formula can still be established in this LV spacetime due to the coupling between the bumblebee field and the Ricci tensor.

Summary: The study investigates the correlation harvesting protocol for mutual information between two Unruh-DeWitt detectors in a static Banados-Teitelboim-Zanelli black hole spacetime. The findings indicate that the harvested mutual information is zero when a detector reaches an event horizon, and extreme Hawking radiation inhibits detectors from harvesting mutual information.

Summary: The study shows that the BTZ black hole may exhibit exotic critical behavior under quantum gravity effects, similar to a van der Waals fluid, with a critical compression factor higher than the universal value. Locally stable/unstable regions can exist maintaining global stability.

Summary: In this paper, we investigated a BTZ black hole with a minimum length introduced by the probability density of the ground state of the hydrogen atom. We analyzed the influence of the minimum length by calculating thermodynamic quantities such as temperature and entropy, and assessed the stability of the black hole by computing the specific heat capacity.

Summary: We have studied charged BTZ black holes in noncommutative spaces using two independent approaches. The first approach revealed the existence of non-static and non-stationary black holes, while the second approach provided stability and physical viability by introducing proper restrictions on the noncommutative parameter. The thermodynamics of the black holes from both approaches were analyzed using a contemporary tunneling formalism.

Summary: This paper studies the thermal state of a two-dimensional conformal field theory and finds that the entanglement patterns of the thermal state can be encoded using an underlying CN-1 cluster algebra or represented geometrically by the cyclohedron CN-1.

Summary: In this paper, we investigate the complexity growth of the tensionless limit of string in the neutral BTZ black hole horizon in massive gravity. When the string approaches the horizon, a novel phenomenon for the growth of the Nambu-Goto action, which differs significantly from tensile string geometry, is observed. The tension of the string is suggested to partially contribute to the action growth. We also propose a potential method to reconstruct complexity from the renormalization group flow.
