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…
Groups of generalized flux transformations in the space of generalized connections
J. M. Velhinho
We present a group of transformations in the space of generalized connections that contains the set of transformations generated by the flux variables of loop quantum gravity. This…
Uniqueness of the Fock representation of the Gowdy and models
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
After a suitable gauge fixing, the local gravitational degrees of freedom of the Gowdy and cosmologies are encoded in an axisymmetric field on the sphere $S^2…
Quantum Gowdy Model: Schrodinger Representation with Unitary Dynamics
Alejandro Corichi, Jeronimo Cortez, Guillermo A. Mena Marugan +1
The linearly polarized Gowdy model is paradigmatic for studying technical and conceptual issues in the quest for a quantum theory of gravity since, after a suitable and almos…
The Quantum Configuration Space of Loop Quantum Cosmology
J. M. Velhinho
The article gives an account of several aspects of the space known as the Bohr compactification of the line, featuring as the quantum configuration space in loop quantum cosmology,…
Uniqueness of the Fock quantization of the Gowdy model
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
After its reduction by a gauge-fixing procedure, the family of linearly polarized Gowdy cosmologies admit a scalar field description whose evolution is governed by a Klein-Go…
