Cone hierarchy and the screening of matter by gravity
Julio Arrechea, Carlos Barceló, Gil Jannes
In a previous paper by some of the authors (Gen. Rel. Grav. 56, 116, 2024), we introduced a novel paradigm with which to understand gravitational phenomena. We called it the Harmon…
The harmonic background paradigm, or why gravity is attractive
Carlos Barceló, Gil Jannes
In a work by Visser, Bassett and Liberati (VBL) [Nucl. Phys. B (Proc. Suppl.) 88, 267 (2000)] a relation was suggested between a null energy condition and the censorship of superlu…
Chronology Protection Implementation in Analogue Gravity
Carlos Barceló, Jokin Eguia Sánchez, Gerardo García-Moreno +1
Analogue gravity systems offer many insights into gravitational phenomena, both at the classical and at the semiclassical level. The existence of an underlying Minkowskian structur…
Conceptual Challenges on the Road to the Multiverse
Ana Alonso-Serrano, Gil Jannes
The current debate about a possible change of paradigm from a single universe to a multiverse scenario could have deep implications on our view of cosmology and of science in gener…
Hawking versus Unruh effects, or the difficulty of slowly crossing a black hole horizon
Luis C. Barbado, Carlos Barceló, Luis J. Garay +1
When analyzing the perception of Hawking radiation by different observers, the Hawking effect becomes mixed with the Unruh effect. The separation of both effects is not always clea…
A tensorial description of particle perception in black-hole physics
Luis C. Barbado, Carlos Barceló, Luis J. Garay +1
In quantum field theory in curved backgrounds, one typically distinguishes between objective, tensorial, quantities such as the Renormalized Stress-Energy Tensor (RSET) and subject…
