Ads Black Holes Demonstrate Enhanced Thermal Radiation and Potential Remnant Formation

The interplay between gravity and electromagnetism profoundly shapes the universe, and recent research explores these connections within the extreme environment of black holes. Ekrem Aydıner from Princeton University, Tekin Dereli from Koç University, and İzzet Sakallı and Erdem Sucu from Eastern Mediterranean University, alongside Ece Seyma Yörük from Koç University, investigate how modifications to gravity, specifically through the Born-Infeld theory, affect the behaviour of black holes in Anti-de Sitter space. This work reveals how these theoretical corrections influence fundamental properties like temperature and light deflection, potentially leaving observable signatures in gravitational lensing and black hole thermodynamics. By examining black hole heat engines and light propagation through plasma, the team demonstrates that Born-Infeld effects, while typically subtle, can become significant in strong gravitational fields, offering new avenues for testing the limits of Einstein’s theory and probing the nature of spacetime itself.

Black Hole Thermodynamics and Information Paradoxes Scientists are exploring the complex relationship between gravity, quantum mechanics, and black holes, investigating fundamental questions about information loss and the ultimate fate of these enigmatic objects. Research focuses on black hole thermodynamics, examining concepts like entropy, heat engines, and phase transitions to understand how these objects behave and evolve. Investigations extend to modified gravity theories, exploring alternatives to Einstein’s general relativity that incorporate nonlinear electromagnetic fields and potentially resolve singularities at the heart of black holes. Current research investigates various black hole models, including those incorporating dilaton fields and regular solutions that lack central singularities. Scientists are also employing tools from fractional calculus to refine calculations and explore quantum effects, such as the Generalized Uncertainty Principle, which modifies the Heisenberg uncertainty principle at extremely small scales. These quantum corrections are crucial for understanding Hawking radiation, the process by which black holes slowly evaporate, and for assessing the possibility of stable remnants after complete evaporation. Astrophysical observations play a vital role in testing these theories, with gravitational lensing serving as a powerful probe of gravity and the properties of compact objects. Scientists analyze how light bends around massive objects, considering the influence of plasma environments and nonlinear electrodynamic effects. Detailed analysis of quasars and compact objects, like neutron stars and black holes, provides valuable data for constraining theoretical models and searching for deviations from general relativity. Furthermore, the study of gravitational waves, generated by merging compact objects, offers a new window into the strong-field regime of gravity. Researchers are applying thermodynamic principles to black holes, treating them as heat engines and exploring their phase transitions, analogous to changes in state observed in ordinary matter. This approach reveals rich behavior, including regions of stability and instability, and allows scientists to calculate efficiencies and predict the behavior of black holes under different conditions. The use of extended phase space, which incorporates pressure and volume as thermodynamic variables, provides a more complete picture of black hole thermodynamics and allows for a deeper understanding of their properties. Theoretical tools, such as fractional calculus and non-extensive thermodynamics, are being employed to refine calculations and explore new avenues of research. These tools allow scientists to go beyond the limitations of traditional approaches and explore more complex scenarios. The investigation of specific fields, like the Kalb-Ramond field from string theory, provides insights into the underlying physics of black holes and their connection to other fundamental theories. Quantum Corrections to EBI-AdS Black Hole Thermodynamics Scientists are meticulously investigating the thermodynamic and optical properties of Einstein-Born-Infeld-Anti-de Sitter (EBI-AdS) black holes, refining calculations of Hawking temperature and incorporating quantum corrections through both the Generalized Uncertainty Principle and modifications to entropy. These analyses reveal enhanced thermal radiation and suggest the possibility of stable remnants forming after black hole evaporation, hinting at the influence of quantum gravity effects. Detailed analysis of gravitational redshift successfully separates the contributions from mass, cosmological constant, electromagnetic charge, and the unique Born-Infeld corrections, demonstrating that the latter are most prominent near the black hole’s event horizon. To quantify light deflection, scientists employ the Gauss-Bonnet theorem, calculating angles in both vacuum and plasma environments. They demonstrate that the presence of dispersive media, like plasma, can either amplify or suppress the nonlinear electrodynamic signatures predicted by the theory. This work pioneers a thermodynamic analysis within extended phase space, treating black hole mass as enthalpy, and reveals complex phase structures with heat capacity transitions between positive and negative values, indicating regions of local stability and instability sensitive to parameter choices. Researchers study black hole heat engines operating in rectangular thermodynamic cycles, achieving efficiencies ranging from 20 to 61 percent of the corresponding Carnot limits, consistent with findings from other AdS black hole systems. Comparison with previous analyses confirms that Born-Infeld corrections to heat engine efficiency are generally small but become appreciable in the strong-field regime where the horizon radius is extremely small. The plasma deflection analysis reveals frequency-dependent refractive modifications, offering additional potential observational channels for detecting these subtle effects.
