Hawking radiation from an analogue bouncing geometry
Alberto García Martín-Caro, Gerardo García-Moreno, Javier Olmedo +1
We propose a setting that simulates Hawking radiation from an analogue bouncing geometry, i.e., a collapsing geometry that reverts its collapse after a finite time, in a setup cons…
Alleviation of anomalies from the non-oscillatory vacuum in loop quantum cosmology
Mercedes Martín-Benito, Rita B. Neves, Javier Olmedo
In this work we investigate observational signatures of a primordial power spectrum with exponential infrared suppression, motivated by the choice of a non-oscillatory vacuum in a…
Regular black holes from Loop Quantum Gravity
Abhay Ashtekar, Javier Olmedo, Parampreet Singh
There is rich literature on regular black holes from loop quantum gravity (LQG), where quantum geometry effects resolve the singularity, leading to a quantum extension of the class…
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…
