Comparative Study of Gravity Models with Observational Constraints from \textit{OHD} and \textit{Pantheon+ datasets}
Anirudh Pradhan, S. A. Salve, V. B. Raut +1
The late-time acceleration of the universe remains one of the most significant open problems in modern cosmology. Modified gravity frameworks such as gravity provide a geome…
Relation-Theoretic Banach Contraction Principle in Topological Spaces with an Application
Md Hasanuzzaman, Abhishikta Das, Sumit Som
In this article, we extend several relation-theoretic notions to topological spaces. We introduce relation preserving contraction mapping into topological spaces and utilize the sa…
Three-qubit W state tomography via full and marginal state reconstructions on ibm_osaka
H. Talath, B. P. Govindaraja, B. G. Divyamani +3
We present a three-qubit quantum state tomography scheme requiring a set of 17 measurement settings, significantly reducing the experimental overhead compared to the conventional 6…
Co-existence of alternative Generalized Chaplygin Gas and other Dark Energies in the Framework of Fractal Universe
Mahasweta Biswas, Rikpratik Sengupta, Ujjal Debnath
We have explored the possibility of the co-existence of two forms of dark energy in the form of an alternative Generalized Chaplygin Gas (GCG) along with a scalar field of field th…
A note on entropy of matter in presence of gravity: status of extensivity of entropy
Saurav Samanta, Bibhas Ranjan Majhi
Entropy of matter in a very strong gravity depends on cross-sectional area of the container of the system -- is being further bolstered by calculating entropy of a monoatomic gas k…
Dark Energy Behavior from Static Equation of State in Non-Minimally Coupled Gravity with Scalar Deformation
N. Myrzakulov, S. H. Shekh, S. R. Bhoyar +1
In this study, we explore the cosmological implications of a modified gravity theory characterized by the function \( f(R, Σ, T) \), where \( R \) is the Ricci scalar, \( Σ\) repre…
