We describe postulates for a novel realist version of relativistic quantum theory or quantum field theory in Minkowski space and other background space-times, and illustrate their application with toy models.

This paper can be seen as an exercise in how to adapt quantum mechanics from a strict relativistic perspective while being respectful and critical towards the experimental achievements of the contemporary theory. The result is a fully observer independent relativistic quantum mechanics for N particle systems without tachyonic solutions. A remaining worry for the moment is Bell’s theorem.

The relativistic KMS condition introduced by Bros and Buchholz provides a link between quantum statistical mechanics and quantum field theory. We show that for the P (φ)2 model at positive temperature, the two point function for fields satisfies the relativistic KMS condition.

We revise the problem of the quantization of relativistic particle models (spinless and spinning), presenting a modified consistent canonical scheme. One of the main point of the modification is related to a principally new realization of the Hilbert space. It allows one not only to include arbitrary backgrounds in the consideration but to get in course of the quantization a consistent relativi...

Abstract The purpose of this paper is to present a parametrized relativistic quantum theory (pRQT) in curved spacetime. formulation pRQT spacetime developed and applied free particle motion flat It provides for calculating probability amplitudes Unlike other formulations dynamics (pRD), work assumes that the metric tensor does not depend on invariant evolution parameter.
