Generalized First Law and Smarr Formula: Beyond Additivity and Extensivity
Usman Zafar, Krishnakanta Bhattacharya, Kazuharu Bamba
The study of black hole thermodynamics becomes a central topic in gravitational physics, where the first law and the Smarr relation establish a deep connection between spacetime ge…
Testing CDM with ANN-Reconstructed Expansion History from Cosmic Chronometers
Yuki Hashimoto, Kazuharu Bamba, Sanjay Mandal
In modern cosmology, the rapid growth of high-precision observational data, along with significant theoretical advances, has intensified the challenge of identifying a robust, mode…
Thermodynamic Topology and Photon Spheres Analysis of Black Holes in Brane-World: Insights from Barrow Entropy
Usman Zafar, Abdul Jawad, Kazuharu Bamba +4
We explore the thermodynamics and geothermodynamics of black holes with Barrow entropy in a brane-world scenario, where the horizon geometry of the black hole is regarded as a frac…
Energy conditions of bouncing solutions in quadratic curvature gravity coupled with a scalar field
Yuki Hashimoto, Kazuharu Bamba, Sanjay Mandal
We examine the validity of classical energy conditions in nonsingular bouncing cosmological solutions arising in quadratic curvature gravity minimally coupled to a scalar field. Fo…
Physical Features of Geometrically Deformed Anisotropic Charged Three-dimensional BTZ Black Holes
Z. Yousaf, Kazuharu Bamba, Mansoor Alshehri +2
This work employs the minimal geometric deformation decoupling scheme to derive interior stellar solutions in the background of an electrically charged BTZ ansatz as a seed metric…
