Rainbow McVittie Horizons in an Expanding Universe
Amani Ashour, Ahmed Farag Ali
We derive the Friedmann dynamics and apparent-horizon thermodynamics of a spatially flat McVittie spacetime in Gravity's Rainbow and construct a consistent non-accreting perfect-fl…
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…
At the Edge of Uncertainty: Decoding the Cosmological Constant value with Bose-Einstein Distribution
Ahmed Farag Ali, Nader Inan
We propose that the observed value of the cosmological constant may be explained by a fundamental uncertainty in the spacetime metric, which arises when combining the principle tha…
Modified gravity/entropic gravity correspondence due to graviton mass
Kimet Jusufi, Ahmed Farag Ali, Abdelrahman Yasser +2
Some time ago, it has been suggested that gravitons can acquire mass in the process of spontaneous symmetry breaking of diffeomorphisms through the condensation of scalar fields [C…
Graviton mass due to dark energy as a superconducting medium: theoretical and phenomenological aspects
Nader Inan, Ahmed Farag Ali, Kimet Jusufi +1
It is well known that the cosmological constant term in the Einstein field equations can be interpreted as a stress tensor for dark energy. This stress tensor is formally analogous…
