Summary: The Renyi and Tsallis entropies are discussed as potential alternatives to the Bekenstein-Hawking area-law entropy, with the importance of maintaining consistency with the notions of Hawking temperature and thermodynamical energy noted. The study also explores the possibility of relating the Renyi and Tsallis entropies to the quantum gravity corrected Bekenstein-Hawking entropy.

Summary: This paper investigates Euler-Heisenberg black holes with quantum electrodynamics (QED) correction, which are embraced by a cavity serving as a boundary of the black hole spacetime and contributing to the system's equilibrium. The thermodynamic properties of the black hole, including phase transitions and phase structures, are explored. The thermodynamic geometry is also studied to diagnose the microscopic interactions of black hole thermodynamic systems.

Summary: The thermodynamic curvature behaves similarly in the Hawking-Page phase transition and the second-order phase transition of the AdS black hole, showing specific patterns related to the spacetime dimension. As the number of spacetime dimensions approaches infinity, the ratio of thermodynamic curvatures in the two different phase transitions tends to a natural constant, indicating a fundamental difference between the two transitions.

Summary: We study the thermodynamic analysis and logarithm corrections of the new Schwarzschild black hole, calculating thermodynamic quantities and analyzing the effects of thermal fluctuations. The area-entropy relation proposed by Bekenstein needs to be corrected, leading to the concept of logarithmic corrections. By evaluating different thermodynamic quantities, we observe that thermal fluctuations affect the stability of small radii black holes and introduce unstable regions due to first-order corrections.

Summary: It has been shown that the exact solutions of the 4D Brans-Dicke-Maxwell (BDM) theory are Reissner-Nordstrom (RN) black holes coupled to a constant scalar field or zero. However, when the scalar potential is not constant or zero, novel black hole solutions affected by a nontrivial scalar hair are obtained. The inclusion of the scalar hair makes the asymptotic behavior of the solutions non-flat and non-AdS, and the theory allows for the occurrence of multi-horizon black holes due to the conformal invariance of Maxwell's electrodynamics, implying anti-evaporation quantum effect. The thermodynamic properties and stability of the BDM black holes are analyzed and found to satisfy the first law of black hole thermodynamics.

Summary: This paper investigates the thermodynamical properties of black holes in Einstein's theory of relativity with a nonlinear electromagnetic field. The transition of the black hole is examined using various properties such as mass, electric charge, coupling constant, and cosmological constant. The thermodynamical aspects of exact black hole solutions are studied, including the calculation of mass, temperature, entropy, Gibbs free energy, specific heat, and critical exponents. The stability of the black hole solution is also explored using specific heat and Gibbs free energy, and the first and second phase changes are observed, showing a P-V criticality similar to the van der Waals phase change. The equation of state and critical exponents are also examined.

Summary: This study used Kramer's escape rate method to investigate the intensity of the phase transition between small and large black hole states. The results show that the phase transition of charged anti-de Sitter (AdS) black holes from small to large presents serious asymmetric features, and the process is dominated by the transition from a small to a large black hole. This study filled a research gap in stochastic process analysis of the first-order phase transition rate in AdS black holes.

Summary: In this study, a bulk wormhole geometry interpolating between horizons of differing size is defined and characteristics of the Hubeny-Rangamani-Takayanagi surface in these geometries are determined. This construction is dual to black hole mesostates, representing an intermediate coarse-graining of states between black hole microstates and the full black hole state. The distinguishability of these objects is analyzed using holographic Holevo information techniques, showing novel phase transition behavior for such systems.

Summary: This paper investigates the thermodynamics of the Horava-Lifshitz black hole at quantum scales, focusing on the non-perturbative quantum correction. The study reveals that the stability of different solutions, such as Kehagius-Sfetsos and Lu-Mei-Pop, is affected differently by the non-perturbative quantum correction. The Lu-Mei-Pop solution remains stable in the presence of the correction.

Summary: In this paper, the Tours-like black hole solution in the regularized self-energy of the electrostatic field is studied in the context of thermodynamics, energy emission, and Gibbs free energy. The Hawking temperature, heat capacity, and thermodynamic stability of the black hole are calculated. The mass of the black hole is determined using the first law of thermodynamics, and the energy emission rate is found to be proportional to the zero-point length parameter. The Gibbs free energy is computed to analyze the phase transition of regularly charged torus-like black holes. The thermodynamic properties are influenced by the thermodynamic pressure represented by the length scale parameter, as well as the effects of pressure, charge, and zero point length.

Summary: This study examines the geometry of anti-de-Sitter (AdS) black hole thermodynamics in four dimensions, comparing it explicitly with normal fluid systems in the extended phase space formalism. The research shows how scalar curvature is proportional to thermodynamic volume for the parameter manifolds considered, and discusses how standard features in normal fluid systems impose restrictions on black hole parameters in extended phase space, potentially leading to physically invalid results in the current literature. A conjecture regarding the equality of correlation lengths of co-existing phases near criticality in charged AdS black hole backgrounds is also examined, with reasonable validity found.

Summary: This paper re-derives the black hole entropy of static spherically symmetric black holes based on the concept of fractal black hole horizon. The temperatures and heat capacities of Schwarzschild, Reissner-Nordstrom, and RN-AdS black holes are calculated, showing that these black holes are thermodynamically stable. The heat capacity of RN-AdS black hole exhibits Schottky anomaly-like behavior, indicating the existence of discrete energy levels and restricted microscopic degrees of freedom.

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.
