Uniqueness of the Fock quantization of scalar fields in a Bianchi I cosmology with unitary dynamics
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +3
The Fock quantization of free scalar fields is subject to an infinite ambiguity when it comes to choosing a set of annihilation and creation operators, choice that is equivalent to…
Callan-Giddings-Harvey-Strominger vacuum in loop quantum gravity and singularity resolution
Alejandro Corichi, Javier Olmedo, Saeed Rastgoo
We study here a complete quantization of a Callan-Giddings-Harvey-Strominger (CGHS) vacuum model following loop quantum gravity techniques. Concretely, we adopt a formulation of th…
Brief review on black hole loop quantization
Javier Olmedo
Here, we present a review about the quantization of spherically-symmetric spacetimes adopting loop quantum gravity techniques. Several models that have been studied so far share si…
Schrödinger-like quantum dynamics in loop quantized black holes
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
We show, following a previous quantization of a vacuum spherically symmetric spacetime carried out in Ref. \cite{gop}, that this setting admits a Schrödinger-like picture. More pre…
Primordial tensor modes of the early Universe
Florencia Benítez Martínez, Javier Olmedo
We study cosmological tensor perturbations on a quantized background within the hybrid quantization approach. In particular, we consider a flat, homogeneous and isotropic spacetime…
Evolution in totally constrained models: Schrödinger vs. Heisenberg pictures
Javier Olmedo
We study the relation between two evolution pictures that are currently considered for totally constrained theories. Both descriptions are based on Rovelli's evolving constants app…
