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…
