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: Recently, thermodynamics has become important in black hole physics and is used to characterize the physical properties and feasibility of many black hole solutions. Meanwhile, Heisenberg algebraic deformations, which predict a lower bound to position and/or momentum, are explored as a theory of quantum gravity. In this paper, a combined deformation of the generalized uncertainty and extended generalized uncertainty principles (EGUP) is considered, and the EGUP-corrected thermal quantities of the rotating charged BTZ black hole are investigated.

Summary: In this paper, the influence of the extended uncertainty principle (EUP) on the thermodynamics of a charged rotating BTZ black hole in (2+1)-dimensional AdS space-time is investigated. EUP-corrected Hawking temperature, pressure, entropy, Gibbs free energy and heat capacity functions are derived. It is observed that EUP-based quantum corrections decrease the pressure and entropy functions in AdS space-time, which only manifests itself in the physically meaningful region for Gibbs free energy and specific heat functions.

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: This paper delves into the thermodynamics of 5-dimensional Schwarzschild AdS(5)xS(5) black hole by considering recently proposed effective models of exponential entropies. The connection between cosmological constant Lambda in the boundary gauge theory and the number of colors N is established, with the chemical potential being considered as the thermodynamic conjugate. By replacing the geometric parameters of the AdS black hole with two thermodynamic parameters in the micro-canonical ensemble, we explore various thermodynamic geometry models and analyze their microscopic forces on the black hole particles.

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: 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: This article analyzes the effects of quantum corrections on the thermodynamics of the Born-Infeld BTZ black hole in massive gravity. The authors find that exponential correction leads to the second point of a first-order phase transition, and quantum correction significantly affects the Helmholtz free energy of larger black holes.

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: The paper explores black hole solutions in three-dimensional massive gravity's rainbow in the cases of Born-Infeld, logarithmic, and exponential theories of nonlinear electrodynamics. Thermodynamics of these models is studied with consideration of first-order quantum correction effects, leading to second-order phase transitions in Born-Infeld and logarithmic models. The modified first law of black hole thermodynamics is derived in the presence of logarithmic corrections.

Summary: We study the physical aspects of quantum field theory in a two stage universe, where it transitions from the inflationary de Sitter stage to the radiation dominated stage. We investigate the time evolution of the primordial vacuum states associated with different modes and show the changes in the power spectrum for a comoving observer as the universe transitions to the radiation stage. Additionally, we develop a methodology to transfer the known result of particle creation in the static de Sitter frame during the transition to the next stage.

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Summary: This paper investigates the effect of gravitational constant variation on the propagation of gravitational waves. By employing two analytical methods, the study finds that variations in the gravitational constant result in amplitude and phase corrections for gravitational waves, and the time variation of the gravitational constant can be constrained through the propagation of gravitational waves.

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
