Muller Discerning Elementary Particles* 2009 22 .pdf application/pdf 9283 854 69 the quantum-mechanical description of similar particles conflicts with Leibniz's Principle of the Identity of Indiscernibles (PII); and that (B) the only way to save PII is of similar particles in all their physical states, pure and mixed, in all infinite-dimensional or finite-dimensional Hilbert spaces can be categorically discerned on the basis of quantum mechanical postulates. The state postulate (StateP) associates some super-selected sector Hilbert space to every given physical system and represents every physicalH S permitted to discern the particles, roughly, all physical relations and all system of a finite number of similar particles, all particles are categorically weakly discernible in every physical state, pure and mixed, The actual proof of the categorical weak discernibility for all particles having nonzero spin magnitude is at bottom a notational variant of the proof of Theorem 1. discernible in every physical state, pure and mixed, for every finitedimensional Hilbert space by using only their spin degrees of freedom. ./cache/work_xqr7gte2cfbefgboy6hasyyzbi.pdf ./txt/work_xqr7gte2cfbefgboy6hasyyzbi.txt
