Summary: This study investigates the influence of the generalized uncertainty principle on phase transitions of the Rutz-Schwarzschild black hole. By analyzing thermodynamic quantities and the generalized uncertainty parameter β, it is found that there are first-order and second-order phase transitions in the Finsler geometry framework, and that the generalized uncertainty parameter significantly affects the generation of black hole remnants.

Summary: In this research, the quantum correction of the Schwarzschild black hole metric is investigated based on the generalized uncertainty principle (GUP). A massless scalar field is assumed, with an effective potential determined by the GUP effect. The phase shift of the scattered wave function is found by approximating the effective potential, and the GUP corrected reflection and transmission coefficients of the scattered radial wave function are calculated using the Posch-Teller method.

Summary: The thermodynamics of a quantum corrected Schwarzschild black hole with AdS background is investigated. The metric of the black hole is introduced, taking into account spherical symmetric quantum fluctuations of spacetime. The free energy of the quantum corrected black hole is obtained based on AdS background using gravity renormalization and saddle-point approximation. The study reveals the significant impact of quantum fluctuations on the energy and entropy, as well as the correction in the radius of the black hole during the Hawking-Page transition.

Summary: By describing the black hole as a statistical ensemble of quantum harmonic oscillators and working in the canonical ensemble, it is shown that in the large-mass black hole limit, the leading contribution to the entropy is the Bekenstein-Hawking term, with a subleading contribution being a logarithmic correction. The number of oscillators is found to scale holographically with the area of the event horizon.

Summary: This study analyzes the effect of quantum corrections on the potential function and quasinormal mode (QNM) of Schwarzschild black holes. The correction terms can alter the singularity structure of the black hole gauge and discretize time and space. Numerical analysis reveals that the effective potential and QNM are greater in scalar fields compared to electromagnetic fields.

Summary: This study reviews the research on the structure of spacetime and singularity within the Schwarzschild black hole using the approaches of loop quantum gravity and generalized uncertainty principle. It provides some new results and reaffirms previous findings that loop quantum gravity maintains finiteness in terms of expansion scalar, Raychaudhuri equation, and Kretschmann scalar within the interior. In the context of generalized uncertainty principle, only two out of the four models studied show similar results, in which the algebra is modified by configuration variables instead of momenta.

Summary: This paper considers the infrared regularization of semi-infinite entangling regions and the formation of islands for regions of finite size in eternal Schwarzschild black holes. It examines whether the properties of complementarity and pure state condition of entanglement entropy can be preserved in the given approximation. A special regularization method satisfying these two properties is proposed. Two fundamental types of finite regions, called mirrorsymmetric (MS) and asymmetric (AS), are derived. For MS regions, a discontinuous evolution of the entanglement entropy of Hawking radiation is discovered due to the finite lifetime of the island. The entanglement entropy of matter for semi-infinite regions in two-sided Schwarzschild black holes does not follow the Page curve. The lifetime of AS regions is bounded from above due to the phenomenon known as Cauchy surface breaking. Shortly before this breaking, the island configuration becomes nonsymmetric. For both types of finite regions, there is a critical size below which the island never dominates. For regions smaller than some other critical size, the island does not emerge. Finally, it is shown that the island prescription does not help to solve the information paradox for certain finite regions.

Summary: This paper investigates the quasinormal modes of the Schwarzschild black hole under the extended generalized uncertainty principle (EGUP) with the minimal length and momentum. The EGUP-corrected black hole metric function is derived, indicating that quantum effects do not alter the event horizon. The perturbation of the quantum-corrected black hole with scalar and electromagnetic fields is considered, and the effect of quantum correction on the time evolution is analyzed.

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: In this paper, a linear generalized uncertainty principle (GUP) was used to analyze the COW experiment and Einstein-Bohr's a photon box experiment. A modified Schwarzschild metric was obtained to calculate quantum corrections in Schwarzschild black hole thermodynamics and tunneling probability. The study found that GUP places restrictions on the minimum mass, size, and temperature of black holes, indicating the presence of a black hole remnant after evaporation.

Summary: We introduce a new version of the Schwarzschild solution that has an inherently discrete structure suitable for quantization. Our approach involves the harmonic mapping of the unit sphere (S (2)) onto itself. This accounts for the quantization of area, while the energy quantum arises from the energy of the harmonic map. Additionally, all thermodynamical quantities are naturally quantized at lower orders.

Summary: This paper investigates the impact of noncommutativity on Hawking radiation and the entropy of the noncommutative Schwarzschild black hole using tunneling formalism. Corrections to the Hawking temperature and entropy of the black hole were obtained through the Hamilton-Jacobi method and the WKB approximation, revealing logarithmic and other types of corrections due to noncommutativity and quantum corrections from the generalized uncertainty principle (GUP).

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.
