Gravitational Memory Beyond Null Infinity through Finite-Distance Carrollian Screens
Felipe Diaz, Sercan Hüsnügil, Oriana Labrin +1
We investigate gravitational memory beyond null infinity by studying finite-distance null hypersurfaces endowed with Carrollian geometry. We show that the intrinsic degenerate geom…
Radiation in Fluid/Gravity and the Flat Limit
Gabriel Arenas-Henriquez, Luca Ciambelli, Felipe Diaz +2
We explore asymptotically locally anti-de Sitter spacetimes exhibiting gravitational radiative behavior, employing null gauges that allow for a well-defined flat limit. The radiati…
Generalized Fefferman-Graham gauge and boundary Weyl structures
Gabriel Arenas-Henriquez, Felipe Diaz, David Rivera-Betancour
In the framework of AdS/CFT correspondence, the Fefferman--Graham (FG) gauge offers a useful way to express asymptotically anti-de Sitter spaces, allowing a clear identification of…
Accelerating Black Holes in dimensions: Holography revisited
Gabriel Arenas-Henriquez, Adolfo Cisterna, Felipe Diaz +1
This paper studies the holographic description of dimensional accelerating black holes. We start by using an ADM decomposition of the coordinates suitable to identify boundar…
Exploring Accelerating Hairy Black Holes in Dimensions: The Asymptotically Locally Anti-de Sitter Class and its Holography
Adolfo Cisterna, Felipe Diaz, Robert B. Mann +1
In the realm of lower-dimensional accelerating spacetimes, it is well-established that the presence of domain walls, which are co-dimension one topological defects, is a necessary…
Thermal fluctuations of black holes with non-linear electrodynamics and charged Renyi entropy
Gabriel Arenas-Henriquez, Felipe Diaz, Yerko Novoa
We extend the charged Renyi entropy to a more general holographic scenario. Coupling an arbitrary non-linear electrodynamics Lagrangian density to AdS gravity, we analyse the therm…
Probing a with non-universal fermion couplings through top quark fusion, decays to bottom quarks, and machine learning techniques
Diego Barbosa, Felipe Díaz, Liliana Quintero +5
The production of heavy mass resonances has been widely studied theoretically and experimentally. Several extensions of the standard model (SM) of particle physics, naturally give…
Logarithmic Corrections, Entanglement Entropy, and UV Cutoffs in de Sitter Spacetime
Gabriel Arenas-Henriquez, Felipe Diaz, Per Sundell
It has been argued that the entropy of de Sitter space corresponds to the entanglement between disconnected regions computable by switching on a replica parameter modeled by th…
de Sitter Entanglement and Conformal Description of the Cosmological Horizon
Felipe Diaz
In this thesis, we aim to understand the microscopic details and origin of the Cosmological Horizon, produced by a static observer in four-dimensional de Sitter (dS) spacetime.…
Liouville description of conical defects in dS, Gibbons-Hawking entropy as modular entropy, and dS holography
Cesar Arias, Felipe Diaz, Rodrigo Olea +1
We model the back-reaction of a static observer in four-dimensional de Sitter spacetime by means of a singular quotient. The set of fixed points of the …
De Sitter Space and Entanglement
Cesar Arias, Felipe Diaz, Per Sundell
We argue that the notion of entanglement in de Sitter space arises naturally from the non-trivial Lorentzian geometry of the spacetime manifold, which consists of two disconnected…
