Diffeomorphism covariance and the quantum Schwarzschild interior
Ian W. Bornhoeft, Rafael G. Dias, Jonathan S. Engle
We introduce a notion of residual diffeomorphism covariance in quantum Kantowski-Sachs (KS), describing the interior of a Schwarzschild black hole. We solve for the family of Hamil…
Spinfoams: Foundations
Jonathan Engle, Simone Speziale
Spinfoams provide a framework for the dynamics of loop quantum gravity that is manifestly covariant under the full four-dimensional diffeomorphism symmetry group of general relativ…
Quantum isotropy and the reduction of dynamics in Bianchi I
Christopher Beetle, Jonathan Steven Engle, Matthew Ernest Hogan +1
The authors previously introduced a diffeomorphism-invariant definition of a homogeneous and isotropic sector of loop quantum gravity, along with a program to embed loop quantum co…
Addendum: EPRL/FK Asymptotics and the Flatness Problem
Jonathan Steven Engle, Wojciech Kaminski, José Ricardo Oliveira
We show that, when an approximation used in this prior work is removed, the resulting improved calculation yields an alternative derivation, in the particular case studied, of the…
Relating loop quantum cosmology to loop quantum gravity: Symmetric sectors and embeddings
Jonathan Engle
In this paper we address the meaning of states in loop quantum cosmology (LQC), in the context of loop quantum gravity. First, we introduce a rigorous formulation of an embedding p…
