Relativistic causality in particle detector models: Faster-than-light signalling and "Impossible measurements"
José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez
We analyze potential violations of causality in Unruh DeWitt-type detector models in relativistic quantum information. We proceed by first studying the relation between faster-than…

Impact of relativity on particle localizability and ground state entanglement
Maria Papageorgiou, Jason Pye
Can a relativistic quantum field theory be consistently described as a theory of localizable particles? There are many known issues with such a description, indicating an answer in…
