Frame dependence of Kochen-Specker contextuality for relativistic spin systems
Jonte R. Hance, Ruben Campos Delgado
We ask whether Kochen-Specker contextuality is Lorentz invariant. On the full Hilbert space, it is, since boosts act unitarily. Restricted to spin, it is not: momentum acts as an e…
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…
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-Za…
Quantum gravitational corrected evolution equations of charged black holes
Ruben Campos Delgado
We explain how quantum gravity, treated as an effective field theory, might modify the evaporative evolution of a four-dimensional, non-extremal, non-rotating, charged black hole.…
Lyapunov exponents in supersymmetric Jackiw-Teitelboim gravity
Ruben Campos Delgado, Stefan Forste
We study supersymmetric Jackiw-Teitelboim (JT) gravity at finite temperature coupled to matter. The matter fields are related to superconformal primaries by AdS/CFT…
Schwarzschild-type black holes in Starobinsky-Bel-Robinson gravity
Ruben Campos Delgado, Sergei V. Ketov
We study physical properties of a Schwarzschild-type black hole in the framework of the recently proposed Starobinsky-Bel-Robinson (SBR) modified theory of gravity, working perturb…
Cylinder quantum field theories at small coupling
Andrei Ioan Dogaru, Ruben Campos Delgado
We show that any 2D scalar field theory compactified on a cylinder and with a Fourier expandable potential is equivalent, in the small coupling limit, to a 1D theory involving…
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 a…
Quantum Gravitational Corrections to the Entropy of a Reissner-Nordström Black Hole
Ruben Campos Delgado
Starting from an effective action for quantum gravity, we calculate the quantum gravitational corrections to the Wald entropy of a four dimensional non-extremal Reissner-Nordström…
On the equivalence of two definitions of conformal primary fields in d > 2 dimensions
Ruben Campos Delgado
Conformal primary fields are of central importance in a conformal field theory with d > 2 spacetime dimensions. They can be defined in two ways. A first definition involves commuta…
