Phenomenological constraints on "impossible" measurements
Jesse Huhtala, Iiro Vilja
In this article, we analyze an "impossible measurement" scenario presented by Sorkin. This scenario involving a joint measurement on spacelike separated systems in an intermediary…

Momentum reconstruction from Unruh-deWitt detectors
Jesse Huhtala, Iiro Vilja
We investigate momentum reconstruction for particle processes observed by Unruh-deWitt detector setups. In particular, we derive the probability distributions for particle momenta…

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…
