Quantum Gowdy model within the new loop quantum cosmology improved dynamics
M Martín-Benito, L J Garay, G A Mena Marugán
The linearly polarized Gowdy model can be regarded as compact Bianchi I cosmologies with inhomogeneous modes allowed to travel in one direction. We study a hybrid quantizatio…
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…
Inhomogeneous Loop Quantum Cosmology: Hybrid Quantization of the Gowdy Model
L. J. Garay, M. Martín-Benito, G. A. Mena Marugán
The Gowdy cosmologies provide a suitable arena to further develop Loop Quantum Cosmology, allowing the presence of inhomogeneities. For the particular case of Gowdy spacetimes with…
A unique Fock quantization for fields in non-stationary spacetimes
Jeronimo Cortez, Guillermo A. Mena Marugan, Javier Olmedo +1
In curved spacetimes, the lack of criteria for the construction of a unique quantization is a fundamental problem undermining the significance of the predictions of quantum field t…
Fock quantization of a scalar field with time dependent mass on the three-sphere: unitarity and uniqueness
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
We study the Fock description of a quantum free field on the three-sphere with a mass that depends explicitly on time, also interpretable as an explicitly time dependent quadratic…
