Spectral Admissibility of Real Observers in Euclidean de Sitter Gravity
Ricardo Espíndola, Ahmed Farag Ali
The Euclidean de Sitter path integral contains the familiar phase associated with conformal negative modes. Maldacena's construction shows that a suitably included real observer ca…
When do real observers resolve de Sitter's imaginary problem?
Ahmed Farag Ali
The universal phase $\rev{\ii}^{D+2}$ of the Euclidean de Sitter path integral obstructs a straightforward state-counting interpretation of the Gibbons--Hawking entropy. Building o…
Mass Without Mass from a Berry--Shifted SU(3) Holonomy Rotor
Ahmed Farag Ali
We identify a local, gauge-invariant mechanism that generates a finite spectral scale in pure SU(3) Yang--Mills theory on a punctured three-ball. Fixing a center sec…
Relational de Sitter State Counting with an SU(3) Clock
Ahmed Farag Ali
Motivated by Maldacena's observer-centric formulation of de~Sitter physics \cite{Maldacena:2024spf}, we develop an observer-dependent state-counting framework in Euclidean de~Sitte…
The Mass Gap of the Space-time and its Shape
Ahmed Farag Ali
Snyder's quantum space-time which is Lorentz invariant is investigated. It is found that the quanta of space-time have a positive mass that is interpreted as a positive real mass g…
