Singularity resolution and unitarity in two-dimensional dilaton black holes with negative central charge
César García-Pérez, F. Javier Marañón-González, José Navarro-Salas +1
We study a one-loop corrected extension of the classical Callan-Giddings-Harvey-Strominger (CGHS) model of two-dimensional dilaton gravity. The effective action combines the non-lo…
The Birth of Gravitational Particle Creation: the Enduring Legacy of Leonard Parker's 1966 Thesis
Antonio Ferreiro, Jose Navarro-Salas, Silvia Pla
This paper offers a historical overview of the origins and enduring significance of gravitational particle creation, a groundbreaking discovery first formulated in Leonard Parker's…
Singularity resolution in the backreacted Schwarzschild geometry from 2D matter with negative central charge
F. J. Marañón-González, A. del Río, J. Navarro-Salas
Two-dimensional dilaton gravity provides a valuable framework to study the dynamics of quantum black holes. These models are often coupled to conformal scalar fields, which capture…
On the renormalization of ultraviolet divergences in the inflationary angular power spectrum
Adrian del Rio, Jose Navarro-Salas
We revise the role that ultraviolet divergences of quantum fields play in slow-roll inflation, and discuss the renormalization of cosmological observables from a space-time perspec…
Adiabatic regularization for spin fields and the renormalized stress-energy tensor
Adrian del Rio, Jose Navarro-Salas
In this article we briefly review the adiabatic renormalization program for spin 1/2 fields in expanding universes. We introduce the method and provide explicit expressions for the…
Adiabatic regularization for massive and massless spin- fields
F. Javier Marañón-González, José Navarro-Salas
The adiabatic regularization method is likely the most direct and intuitive renormalization scheme for FLRW cosmologies. The method requires one to start with a nonvanishing mass,…
