Local measurements in Relativistic Quantum Information: localization and signaling
Papageorgiou, Maria-Eftychia (University of Waterloo, 2023-12-12)In this thesis, we study some foundational aspects of detector models in quantum field theory (QFT) related to signaling and localization, and we analyze certain frictions with relativistic causality. We characterize the ... -
What is a field, what is a particle?
Papageorgiou, Maria-Eftychia (University of Waterloo, 2019-01-25)Much of the structure of quantum field theory (QFT) is predicated on the principle of locality. Adherence to locality is achieved in Algebraic QFT (AQFT) by the association of algebras of observables with regions of ...
