Engineering of Non-Hermitian Trajectories and Phase Structure in an Open Bose-Hubbard Model via Rate Operator Transformations
Jaakko Luomala, Kimmo Luoma, Iiro Vilja +1
Non-Hermitian evolution can be realized through post-selection on stochastic pure-state trajectories arising in continuously monitored open quantum systems. The rate operator forma…
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…
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…
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…
Practical Derivations of Fermion and Gauge Boson Reduction Formulae in Curved Spacetimes
Jesse Huhtala, Iiro Vilja
LSZ-type reduction formulae are derived for gauge fields and fermions in curved spacetime. The formulae are derived using a conserved current method applicable also to flat spaceti…
