Absorption spectrum and greybody factors of charged black holes in loop quantum gravity
Marco A. A. de Paula, Valdir B. Bezerra, Luiz C. S. Leite
In the last few decades, singularity-free black holes (BHs) obtained in the framework of Loop Quantum Gravity (LQG) have gained attention in the literature. These compact objects r…
LIV-Decoherence on Gravitational Cat States
Iarley P. Lobo, Kelvin Sampaio, Gislaine Varão +2
Inspired by approaches based on the stochastic generalized uncertainty principle, we propose a Lindblad equation derived from the quantization of a stochastic modified dispersion r…
Coherence and Entanglement in a Non-commutative Spacetime
Iarley P. Lobo, Gislaine Varão, Giulia Gubitosi +2
We investigate the emergence of quantum coherence and quantum correlations in a two-particle system with deformed symmetries arising from the quantum nature of spacetime. We demons…
Ellis-Bronnikov Wormholes in Asymptotically Safe Gravity
G. Alencar, V. B. Bezerra, C. R. Muniz +1
In this paper, we investigate the simplest wormhole solution - the Ellis-Bronnikov one - in the context of the Asymptotically Safe Gravity (ASG) at the Planck scale. We work with t…
Black holes with a fluid of strings
J. M. Toledo, V. B. Bezerra
We obtain an exact solution of Einstein's equations for a charged, static and spherically symmetric body, surrounded by a fluid of strings and with a cosmological constant. This co…
Self-force on a scalar particle in a class of wormhole spacetimes
V. B. Bezerra, Nail R. Khusnutdinov
We consider the self-energy and the self-force for scalar massive and massless particles at rest in the wormhole space-time. We develop a general approach to obtain the self-force…
