Transforming singular black holes into regular black holes sourced by nonlinear electrodynamics
Pedro Cañate, Santiago Esteban Perez Bergliaffa
We present a procedure that transforms a singular, asymptotically flat, static and spherically symmetric black hole into a regular black hole spacetime. The regular black hole is a…
Particle Production in Accelerated Thin Bubbles
Florencia Anabella Teppa Pannia, Santiago Esteban Perez Bergliaffa, Nelson Pinto-Neto
We investigate the creation of scalar particles inside a region delimited by a bubble which is expanding with non-zero acceleration. The bubble is modelled as a thin shell and play…
Quantum relaxation in a system of harmonic oscillators with time-dependent coupling
F. B. Lustosa, S. Colin, S. E. Perez Bergliaffa
In the context of the de Broglie-Bohm pilot wave theory, numerical simulations for simple systems have shown that states that are initially out of quantum equilibrium - thus violat…
Primordial Magnetogenesis in a Bouncing Universe
E. Frion, N. Pinto-Neto, S. D. P. Vitenti +1
We investigate primordial magnetogenesis and the evolution of the electromagnetic field through a quantum bounce, in a model that starts in the far past from a contracting phase wh…
Cosmography and the redshift drift in Palatini theories
F. A. Teppa Pannia, S. E. Perez Bergliaffa, N. Manske
We present an application to cosmological models in theories within the Palatini formalism of a method that combines cosmography and the explicit form of the field eq…
On the emergence of the CDM model from self-interacting Brans-Dicke theory in
Luz Marina Reyes, Santiago Esteban Perez Bergliaffa
We investigate whether a self-interacting Brans-Dicke theory in without matter and with a time-dependent metric can describe, after dimensional reduction to , the FLRW m…
