Propagation-Distance Limit for a Classical Nonlocal Optical System
Salman Sajad Wani, Xiaoping Shi, Saif- Al-Kuwari +2
We derive closed-form analog quantum-speed-limit (QSL) bounds for highly nonlocal optical beams whose paraxial propagation is mapped to a reversed (inverted) harmonic-oscillator ge…
Consequences of Undecidability in Physics on the Theory of Everything
Mir Faizal, Lawrence M. Krauss, Arshid Shabir +1
General relativity treats spacetime as dynamical and exhibits its breakdown at singularities. This failure is interpreted as evidence that quantum gravity is not a theory formulate…
A Novel Construction of de Sitter Vacua in Heterotic String Theory
Mir Faizal, Arshid Shabir
We present a concrete string-theoretic mechanism that generates four-dimensional de Sitter vacua from non-geometric R-flux compactifications of heterotic string theory. The constru…
Can quantum gravity be both consistent and complete?
Mir Faizal, Lawrence M. Krauss, Arshid Shabir +2
General relativity, despite its profound successes, fails as a complete theory due to presence of singularities. While it is widely believed that quantum gravity has the potential…
Holographic Consequences of Heterotic String Theory beyond its Supergravity Approximation
Leon Berdichevsky Acosta, Salman Sajad Wani, Arshid Shabir +6
In this work, we study the effects of stringy corrections on the low energy effective action derived from heterotic string theory beyond its supergravity approximation. Compactifyi…
