Representation of the causal logic for the Dirac system and the electron
Domenico P. L. Castrigiano, Carmine De Rosa, Valter Moretti
We construct a covariant representation of the causal logic for the Dirac system and the electron, based on the conserved Dirac probability current and a general current-to-localiz…
Spatial Localization of Relativistic Quantum Systems: The Commutativity Requirement and the Locality Principle. Part II: A Model from Local QFT
Valter Moretti
This paper is the second and final part of a two-part study. We construct positive-energy relativistic spatial localization observables in Minkowski spacetime within standard quant…
Spatial Localization of Relativistic Quantum Systems: The Commutativity Requirement and the Locality Principle. Part I: A General Analysis
Valter Moretti
We investigate whether commutativity is necessary to represent relativistic locality for localization observables of relativistic quantum systems in Minkowski spacetime. A well kno…
Achronal localization and representation of the causal logic from a conserved current, application to the massive scalar boson
Domenico P. L. Castrigiano, Carmine De Rosa, Valter Moretti
Only recently the concept of achronal localization has been developed as the adequate frame for the description of the localizability of a relativistic quantum mechanical system. H…
