Particle Detectors from Localized Quantum Field Theories
T. Rick Perche, José Polo-Gómez, Bruno de S. L. Torres +1
We present a fully relativistic model for localized probes in quantum field theory. Furthermore, we show that it is possible to obtain particle detector models from localized quant…

Causality and signalling in non-compact detector-field interactions
José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez
In this paper we analyze the problem of "apparent" superluminal signalling and retrocausation that can appear for particle detector models when considering non-compactly supported…
