From Rényi Entropy to the Feynman Path Integral

Authors: Ervin Goldfain
Comments: 17 Pages.

In this sequel to [17 - 18], we argue that Rényi Entropy is organically tied to the FeynmanPath Integral formalism of Quantum Field Theory (QFT).

Problems with Nontrivial Symmetrizations of Hamiltonian Operators

Authors: Jouni Puuronen
Comments: 11 Pages.

We discover an example of an infinite collection of simple quantum systems that all have the same classical limit, and recognize this as a problem, because the correct quantization of the example classical system is then not known. Our example contradicts Born-Jordan quantization theory, meaning that at least other one must contain a mistake. We discuss the related possible difficulties with the quantum mechanical description of a charged particle in a magnetic field, but eventually conclude that these difficulties maybe are not so severe after all.
