Normalizing Fock space states in static spacetimes
Jesse Huhtala, Iiro Vilja
In quantum field theory, sharp momentum states have to be normalized to be in Fock space. We investigate different normalization schemes, both box normalization and wave packets. T…

Packaging particles in curved spacetimes
Jesse Huhtala, Iiro Vilja
Scattering calculations in curved spacetime are technically complicated and, in the case of a general spacetime metric, quite impossible. Even in the cases where perturbative scatt…

Perturbative approaches to quantum field theory in curved space-time
Jesse Huhtala, Nicola Lo Gullo, Iiro Vilja
Despite the large amount of work done in quantum field theory in curved space-times, there are not great many results available for perturbative calculations of particle processes…
