Unitary evolution and uniqueness of the Fock representation of Dirac fields in cosmological spacetimes
Jerónimo Cortez, Beatriz Elizaga Navascués, Mercedes Martín-Benito +2
We present a privileged Fock quantization of a massive Dirac field in a closed Friedmann-Robertson-Walker cosmology, partially selected by the criteria of invariance of the vacuum…

Quantum unitary dynamics in cosmological spacetimes
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
We address the question of unitary implementation of the dynamics for scalar fields in cosmological scenarios. Together with invariance under spatial isometries, the requirement of…
