Compact, long-range and vacuumless regimes controlled by scalar fields in two-dimensional flat and five-dimensional warped geometries
Elisama E. M. Lima, Dionisio Bazeia
We investigate the presence of compact, long-range, and vacuumless regimes in models described by real scalar fields in 2D flat and 5D warped geometries. In the two-dimensional cas…
Anisotropic models in LQC with GBP polymerisation
D. A. Cook, A. Olimpieri, I. P. R. Baranov +2
Polymer models are effective in describing quantum gravity effects around the initial singularity, leading to its replacement by bouncing surfaces on which the curvature and densit…
Thermodynamics of effective loop quantum black holes
F. G. Menezes, H. A. Borges, I. P. R. Baranov +1
We study the thermodynamics of a non-singular black hole model with effective quantum corrections motivated by Loop Quantum Gravity (LQG). The effective geometry has a transition s…
Dark sector interactions in light of weak lensing data
M. Benetti, P. T. Z. Seidel, C. Pigozzo +3
The current observational tensions in the standard cosmological model have reinforced the research on dynamical dark energy, in particular on models with non-gravitational interact…
Non-singular naked solutions in quantum spacetime
I. P. R. Baranov, H. A. Borges, F. C. Sobrinho +1
Polymer models have been used to describe non-singular quantum black holes, where the classical singularity is replaced by a transition from a black hole to a white hole. In a prev…
Scalar fields, localized structures and the Starobinsky model
D. Bazeia, Elisama E. M. Lima
This work deals with the presence of localized static structures in the real line, described by relativistic real scalar fields in two spacetime dimensions. We consider models feat…
