Summary: This study considers a small correction to the Maxwell field and shows that the resultant black hole solutions undergo reentrant phase transition, leading to novel phase behavior. The nonlinearity parameter α<=4q(2)/7 provides a new classification in the canonical ensemble of extended phase space. For α<4q(2)/7, there is a reentrant phase transition, while for α=4q(2)/7, there is no phase transition below (at) the critical point. Additionally, small and large black holes are thermodynamically distinguishable for temperatures and pressures higher than the critical ones.

Summary: This study discusses the thermodynamic properties of Reissner-Nordstrom-de Sitter (RN-dS) space-time and finds that the coexistent curve of Hawking-Page temperature and pressure is a closed curve with upper bounds. This has significant implications for understanding the evolution and microstructure of de Sitter space-time.

Summary: Research suggests that overcharging a charged Taub-NUT regular black hole is possible through the scattering of a charged field and absorption of a charged particle. Both near-extremal and extremal black holes cannot be overcharged through charged scalar field scattering. While the event horizon of a near-extremal charged Taub-NUT regular black hole may be destroyed by absorption of a charged particle, it may not be overcharged if charge and energy cross the event horizon in a continuous path.

Summary: The study investigates the pair production of charged scalar particles in a near extremal RN-AdS(5) black hole, revealing a concise relation between pair production rate and absorption cross section ratio in the full spacetime and near horizon region. The holographic descriptions of pair production in the IR CFT and UV CFT are analyzed using AdS(2)/CFT1 and AdS(5)/CFT4 correspondences, providing a complete description of scalar pair production in a near extremal RN-AdS(5) black hole.

Summary: In this paper, the quantum correction on the thermodynamics of the Reissner-Nordstrom black hole in the presence of quintessence matter associated with dark energy is investigated. The modified Hawking temperature, heat capacity, and entropy functions of the black hole are derived. It is found that the modified uncertainty principles and normalization factor have significant effects on the thermodynamic properties of the black hole, and graphical methods are used to compare the findings within different uncertainty principles.

Summary: This study introduces two novel classes of nonlinearly charged black hole solutions that are coupled to logarithmic and exponential theories of nonlinear electrodynamics in the context of massive gravity theory. The study calculates the thermodynamic and conserved quantities of the black holes and investigates their thermal stability and global stability. By comparing the results obtained from different methods and considering the thermodynamic pressure, the critical behavior of the black holes in the extended phase space is also studied.

Summary: This article investigates the dynamics of neutral and charged particles in a magnetic field around a Reissner-Nordstrom black hole surrounded by quintessence, considering Noether symmetries and conservation laws in the corresponding spacetime. The study explores the effects of angular momentum, quintessence parameter, and magnetic field on the particles' dynamics, and also examines the orbit stability of the spacetime using the Lyapunov exponent.

Summary: This study tests the weak cosmic censorship conjecture for the Reissner-Nordstrom-de Sitter black hole surrounded by perfect fluid dark matter, showing that even in a realistic scenario with cosmological parameters, the black hole cannot be overcharged unless the induced fields by dark matter and cosmological parameters are completely balanced. Additionally, it is found that a certain threshold limit exists beyond which the black hole cannot be overcharged, indicating that the effect of the cosmological constant dominates over the effect of perfect fluid dark matter in the overcharging process.

Summary: In this study, the thermal stability of a charged non-rotating black hole is examined, revealing that it is quasi stable but not completely stable, contrary to Hawking's prediction. The black hole exhibits phase transition and attempts to resist decay under Hawking radiation, without ultimate success.

Summary: In this study, we analytically investigate the scalarization of higher-dimensional charged Reissner-Nordstrom black hole. It is found that a static massive scalar field, which is non-minimally coupled to the Gauss-Bonnet invariant, can be supported by the higher-dimensional black hole in the super-critical charge regime. Moreover, we demonstrate that the static massive scalar shell can be incredibly thin in the large mass regime.

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.
