It is shown that, in this limit, time correlations cancel out and that Newtonian dynamics is recovered for the system in a natural way.6 p.application/pdfeng(c) The American Physical Society, 1985Mecànica quànticaTeoria de camps (Física)Relativitat especial (Física)Quantum theoryField theory (Physics)Special relativity (Physics)1/c expansion of a separable model of direct-interaction typeinfo:eu-repo/semantics/article4767info:eu-repo/semantics/openAccess
