Quantum geometry and black holes
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
We summarize our work on spherically symmetric midi-superspaces in loop quantum gravity. Our approach is based on using inhomogeneous slicings that may penetrate the horizon in cas…
Observational constraints on anisotropies for bouncing alternatives to inflation
Ivan Agullo, Javier Olmedo, Edward Wilson-Ewing
We calculate how primordial anisotropies in the background space-time affect the evolution of cosmological perturbations for bouncing alternatives to inflation, like ekpyrosis and…
Towards a quantum notion of covariance in spherically symmetric loop quantum gravity
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
The covariance of loop quantum gravity studies of spherically symmetric space-times has recently been questioned. This is a reasonable worry, given that they are formulated in term…
Breaking of isospectrality of quasinormal modes in nonrotating loop quantum gravity black holes
Daniel del-Corral, Javier Olmedo
We study the quasinormal frequencies of three effective geometries of nonrotating regular black holes derived from loop quantum gravity. Concretely, we consider the Ashtekar-Olmedo…
