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…

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…

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…
