Unitary evolution as a uniqueness criterion
Jeronimo Cortez, Guillermo A. Mena Marugan, Javier Olmedo +1
We briefly review the use of unitary evolution as a uniqueness criterion in the selection of quantum representations, in the context of scalar fields in non-stationary situations.

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.

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…
