The Stringy Photon Sphere
Ahmed Sheta
The S matrix on an asymptotically-flat Schwarzschild black hole is studied as a function of position on . We derive the lightcone singularities that arise in the S mat…
Self-Dual Yang-Mills in AdS
Simon Heuveline, Romain Ruzziconi, Ahmed Sheta +1
Quantum Yang-Mills theory in Euclidean AdS with Neumann boundary conditions is studied as a function of the complex couplings $\frac{1}{g_\pm^2} \equiv \frac{1}{g^2}\mp \frac{i…
A Formal Framework for Critical-Mass Collapse in Online Multiplayer Games
Ahmed Sheta
Online multiplayer games are population-dependent systems whose playability depends on the continued presence of an active player base. We propose a formal framework for reasoning…
Soft Algebras in AdS from Light Ray Operators in CFT
Ahmed Sheta, Andrew Strominger, Adam Tropper +1
Flat Minkowski space (M) and AdS can both be conformally mapped to the Einstein cylinder. The maps may be judiciously chosen so that some null generators of the $\mathcal{I…
