Frame dependence of Spekkens' contextuality for relativistic spin systems
Ruben Campos Delgado
We show that the operational definition of contextuality introduced by Spekkens is, in general, not Lorentz invariant. Specifically, we consider an explicit example with particle s…
Ruling out nonlinear modifications of quantum theory with contextuality
Ruben Campos Delgado, Martin Plávala
Nonlinear modifications of quantum theory are considered potential candidates for the theory of quantum gravity, with the intuitive argument that since Einstein field equations are…
Quantum gravitational corrections to the geometry of charged AdS black holes
Behnam Pourhassan, Ruben Campos Delgado, Sudhaker Upadhyay +2
We study the quantum gravitational corrections to the geometry of a four-dimensionalcharged (Reissner-Nordström) Anti de Sitter black hole starting from an effective field theory…
Traversable Wormholes in Constant Curvature Black Holes
Ankit Anand, Ruben Campos Delgado, Daris Samart
This paper investigates the massive gauge field within spacetime context from a quotient of the constant curvature black hole. We investigate how the matter field's…
Einstein-Grisaru-Zanon gravity
Ruben Campos Delgado, Sergei V. Ketov
The leading -correction to the gravitational low-energy effective action of closed (type II) superstring theory in four-spacetime dimensions defines the Einstein-Grisaru-Z…
