The Coupling of Shape Dynamics to Matter
Henrique Gomes
Shape Dynamics (SD) is a theory dynamically equivalent to vacuum General Relativity (GR), which has a different set of symmetries. It trades refoliation invariance, present in GR,…
Prescriptions in Loop Quantum Cosmology: A comparative analysis
Guillermo A. Mena Marugan, Javier Olmedo, Tomasz Pawlowski
Various prescriptions proposed in the literature to attain the polymeric quantization of a homogeneous and isotropic flat spacetime coupled to a massless scalar field are carefully…
A uniqueness criterion for the Fock quantization of scalar fields with time dependent mass
Jerónimo Cortez, Guillermo A. Mena Marugán, Javier Olmedo +1
A major problem in the quantization of fields in curved spacetimes is the ambiguity in the choice of a Fock representation for the canonical commutation relations. There exists an…
Uniqueness of the Fock quantization of fields with unitary dynamics in nonstationary spacetimes
Jeronimo Cortez, Guillermo A. Mena Marugan, Javier Olmedo +1
The Fock quantization of fields propagating in cosmological spacetimes is not uniquely determined because of several reasons. Apart from the ambiguity in the choice of the quantum…
