Relativistic covariance and interpretation of quantum mechanics
Description
Lorentz and CPT invariance require that the predictive evolution of a quantal system from a preparation and the retrodictive evolution of the same system towards a later measurement are treated on the same footing. It is therefore submitted that between the two pseudo-time instants σ1 and σ2 (in the TONONAGA-SCHWINGER senses) where the preparation and the measurement are respectively performed, the system is in the course of transiting from PHI(σ1) to PSI(σ2). Before introducing this concept we consider briefly the overall scheme of relativistic quantum mechanics, and discuss the interpretation of the FEYNMAN propagator
Abstract (French)
LORENTZ et CPT-invariances imposent de ne pas privilegier l'evolution predictive d'un systeme quantique a partir d'une preparation de l'evolution retrodictive du meme systeme vers une mesure ulterieure. L'on propose donc le concept qu'entre les deux pseudo-instants σ1 et σ2 (au sens de TOMONAGA-SCHWINGER), ou sont respectivement faites la preparation et la mesure, le systeme est en train de transiter de l'etat PHI(σ1) a l'etat PSI(σ2). Prealablement a l'introduction de ce concept, on survole le scheme de la mecanique quantique relativiste, puis l'on discute de l'interpretation du propagateur de FEYNMAN en dissociant ce qui, dans sa definition, est essentiel, de ce qui est contingentAdditional details
