The Vacuum State of Primordial Fluctuations in Hybrid Loop Quantum Cosmology
Beatriz Elizaga Navascués, Daniel Martín de Blas, Guillermo A. Mena Marugán
We investigate the role played by the vacuum of the primordial fluctuations in hybrid Loop Quantum Cosmology. We consider scenarios where the inflaton potential is a mass term and…
Loop quantization of the Gowdy model with local rotational symmetry
Daniel Martín de Blas, Javier Olmedo, Tomasz Pawłowski
We provide a full quantization of the vacuum Gowdy model with local rotational symmetry. We consider a redefinition of the constraints where the Hamiltonian Poisson-commutes with i…
Inclusion of matter in inhomogeneous loop quantum cosmology
Daniel Martín-de Blas, Mercedes Martín-Benito, Guillermo A. Mena Marugán
We study the hybrid quantization of the linearly polarized Gowdy model with a massless scalar field with the same symmetries as the metric. For simplicity, we quantize its re…
Quantization of the massless scalar field in de Sitter spacetime with unitary dynamics
Jeronimo Cortez, Daniel Martin-de Blas, Guillermo A. Mena Marugan +1
We present a Fock quantization with unitary dynamics for the massless scalar field in de Sitter spacetime.
Inhomogenous loop quantum cosmology with matter
Daniel Martín-de Blas, Mercedes Martín-Benito, Guillermo A. Mena Marugán
The linearly polarized Gowdy model with a massless scalar field with the same symmetries as the metric is quantized by applying a hybrid approach. The homogeneous geometry de…
Massless scalar field in de Sitter spacetime: unitary quantum time evolution
Jeronimo Cortez, Daniel Martin-de Blas, Guillermo A. Mena Marugan +1
We prove that, under the standard conformal scaling, a massless field in de Sitter spacetime admits an O(4)-invariant Fock quantization such that time evolution is unitarily implem…
