Uniqueness of the Fock quantization of scalar fields in a Bianchi I cosmology with unitary dynamics
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +3
The Fock quantization of free scalar fields is subject to an infinite ambiguity when it comes to choosing a set of annihilation and creation operators, choice that is equivalent to…
Dirac fields in flat FLRW cosmology: Uniqueness of the Fock quantization
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +2
We address the issue of the infinite ambiguity that affects the construction of a Fock quantization of a Dirac field propagating in a cosmological spacetime with flat compact secti…
Hybrid Models in Loop Quantum Cosmology
B. Elizaga Navascués, M. Martín-Benito, G. A. Mena Marugán
In the framework of Loop Quantum Cosmology, inhomogeneous models are usually quantized by means of a hybrid approach that combines loop quantization techniques with standard quantu…
Uniqueness of the Fock quantization of Dirac fields in 2+1 dimensions
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +2
We study the Fock quantization of a free Dirac field in 2+1-dimensional backgrounds which are conformally ultrastatic, with a time-dependent conformal factor. As it is typical for…
