Local spinfoam expansion in loop quantum cosmology
Adam Henderson, Carlo Rovelli, Francesca Vidotto +1
The quantum dynamics of the flat Friedmann-Lemaitre-Robertson-Walker and Bianchi I models defined by loop quantum cosmology have recently been translated into a spinfoam-like forma…
Hybrid Quantization: From Bianchi I to the Gowdy Model
Mercedes Martín-Benito, Guillermo A. Mena Marugán, Edward Wilson-Ewing
The Gowdy cosmologies are vacuum solutions to the Einstein equations which possess two space-like Killing vectors and whose spatial sections are compact. We consider the simplest o…
Loop quantum cosmology of Bianchi type IX models
Edward Wilson-Ewing
The loop quantum cosmology "improved dynamics" of the Bianchi type IX model are studied. The action of the Hamiltonian constraint operator is obtained via techniques developed for…
Surface terms, Asymptotics and Thermodynamics of the Holst Action
Alejandro Corichi, Edward Wilson-Ewing
We consider a first order formalism for general relativity derived from the Holst action. This action is obtained from the standard Palatini-Hilbert form by adding a topological-li…
