Quantum corrections in thermodynamics of black holes modified by nonlinear electrodynamics and their observational signatures
Bibliographic record
Abstract
This work explores the thermodynamic and observational properties of black holes (BHs) influenced by nonlinear electrodynamics (NED) while incorporating quantum corrections. We analyze modifications to BH thermodynamics due to NED effects, focusing on quantum-corrected entropy, Hawking temperature, and phase transitions. Our study introduces a new framework that integrates quark–antiquark confinement effects into the NED formalism, revealing substantial deviations in the thermodynamic stability of BHs. The interplay between EC entropy and classical Bekenstein–Hawking entropy is examined, leading to refined predictions for key thermodynamic quantities. Additionally, we investigate the observational signatures of NED BHs, including their shadows, quasinormal modes (QNMs), and gravitational redshift. By performing a photon sphere analysis, we compute the modifications in BH shadows and identify potential observational markers linked to NED effects. Moreover, we derive the QNMs of these BHs, shedding light on their stability and dynamical behavior under scalar perturbations. Gravitational redshift calculations further illustrate how NED alters the spectral properties of emitted radiation near BHs, presenting new possibilities for testing these effects through astronomical observations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
