Stress-Energy Tensor for Modified General Relativity with Quantum-Deformed Metric in Riemann Spacetime
A. Tawfik, Saleh O. Allehabi, A. A. Alshehri +2
The generalized noncommutative Heisenberg algebra, which is based on the generalized uncertainty principle, imposes a minimal length uncertainty on quantum mechanics (QM), on one h…
Reevaluation of Inflationary Dynamics in Extended General Relativity with Perturbatively and Tensorially Structured Conformal Metric
Swapnil K. Singh, Saleh O. Allehabi, Azzah A. Alshehri +2
Based on the conventional metric tensor and driven by a nearly constant energy density, cosmic inflation, characterized by a remarkably accelerated expansion, was proposed as an ea…
Quantum-Deformed Phase-Space Geometry and Emergent Inflation in Effective Four-Dimensional Spacetime
Swapnil Kumar Singh, Saleh O. Allehabi, Azzah A. Alshehri +3
We develop a phase-space approach to quantum-deformed gravity. Reducing it to an effective four-dimensional spacetime structure facilitates reanalyzing cosmic inflation and quantum…
GUP/BEB correspondence
Ahmed Farag Ali
We develop a fully expectation--value formulation of the GUP/Bekenstein--bound (BEB) correspondence, building on \cite{Ali:2024tbd,Ali:2022ckm,Ali:2022ulp}. Using Dirac's commutato…
Deriving the Cosmological Constant and Nature's Constants from SU(3) Confinement Volume
Malak Ali, Ahmed Farag Ali
We explore the interplay between three well-established physical principles: QCD confinement, the Third Law of Thermodynamics, and holography, and examine how their combined implic…
Vacuum Homogeneous and Nonhomogeneous Metrics with Conventional and Quantized Metric Tensor: Singular or Nonsingular Solution
A. Tawfik, S. G. Elgendi, M. Hanafy
To investigate whether the Universe underwent a singularity or maintained a nonsingular state, we carry out analytical and numerical analyses of the evolution of the Raychaudhuri e…
