Causality and Localization Operators

subject

Causality (physics)Physics Quantum Physics causality Zero (complex analysis)FOS: Physical sciences General Physics and Astronomy Hegerfeldt's theorem Quantum Physics (quant-ph)Scalar field Quantum fluctuation Mathematical physics

description

The evolution of the expectation values of one and two points scalar field operators and of positive localization operators, generated by an istantaneous point source is non local. Non locality is attributed either to zero point vacuum fluctuations, or to non local operations or to the microcausality principle being no satisfied.
