Loop quantum black hole extensions within the improved dynamics
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
We continue our investigation of an improved quantization scheme for spherically symmetric loop quantum gravity. We find that in the region where the black hole singularity appears…
Primordial scalar power spectrum from the hybrid approach in loop cosmologies
Bao-Fei Li, Javier Olmedo, Parampreet Singh +1
We compare the primordial scalar power spectra in the loop cosmological models using the effective dynamics of the hybrid approach to cosmological perturbations in which the backgr…
Properties of a recent quantum extension of the Kruskal geometry
Abhay Ashtekar, Javier Olmedo
Recently it was shown that, in an effective description motivated by loop quantum gravity, singularities of the Kruskal space-time are naturally resolved [1,2]. In this note we exp…
Spherically symmetric loop quantum gravity: analysis of improved dynamics
R. Gambini, J. Olmedo, J. Pullin
We study the "improved dynamics" for the treatment of spherically symmetric space-times in loop quantum gravity introduced by Chiou {\em et al.} in analogy with the one that has be…
xAct Implementation of the Theory of Cosmological Perturbation in Bianchi I Spacetimes
Ivan Agullo, Javier Olmedo, V. Sreenath
This paper presents a computational algorithm to derive the theory of linear gauge invariant perturbations on anisotropic cosmological spacetimes of the Bianchi I type. Our code is…
Observational consequences of Bianchi I spacetimes in loop quantum cosmology
Ivan Agullo, Javier Olmedo, V. Sreenath
Anisotropies generically dominate the earliest stages of expansion of a homogeneous universe. They are particularly relevant in bouncing models, since shears grow in the contractin…
