Nonlocal Hidden-Variable Theories and Quantum Mechanics: An Incompatibility Theorem
It is argued that among possible nonlocal hidden-variable theories a particular class (called here ‘‘crypto-nonlocal’’ or CN) is relatively plausible on physical grounds. CN theories have the property that (for example) the two photons emitted in an atomic cascade process are indistinguishable in their individual statistical properties from photons emitted singly, and that in the latter case th...
متن کاملS-Theorem: Incompatibility of Scale Invariance and Hermiticity of Hamiltonian
In this brief note, it has been shown that scale invariance (i.e the scaling algebra [D,H] = izH) is incompatible with Hamiltonian (H) being Hermitian on a domain containing the state D|E〉, where |E〉 is the non-zero energy eigenstate and D generates scale transformation. The claim has been elucidated with the strongly coupled regime of inverse square potential and the free particle as concrete ...
