The Quantum Relativity and Dynamical Spacetime

TL;DR

This paper explores the limitations of current quantum field theory under special relativity and proposes the need for a dynamical theory of quantum fields that incorporates a more general, possibly relativistic, spacetime framework.

Contribution

It introduces the concept of a dynamical spacetime in quantum theory, extending beyond the kinematic framework of traditional quantum field theory.

Findings

Current QFT is a kinematic limit of a more general dynamical theory.

Relativistic principles may not be universally applicable to all quantum systems.

A new dynamical approach could better describe complex sub-atomic interactions.

Abstract

Quantum field theory (QFT) based on the principles of special relativity (SR) and it is in fact the \emph{kinematic theory of fields}. The root assumption is that there is "relativistic description" of \emph{any} isolated quantum system in the so-called class of inertial systems even if the internal interactions or self-interactions lie outside of the formal QFT itself. In such a situation we cannot be sure that the principle of relativity in the present form is universally applicable since this principle arose from the Maxwell electrodynamics. As we know Einstein was insisted to generalize this principle in the attempt to find the relativistic description of gravity. Together with this the Galileo-Newton principle of inertia was modified with essential reservations \cite{Einstein_1921,Le13,Le15,Le16,Le18}. New kind of sub-atomic interactions have definitely more complicated nature and mostly unknown laws. It is clear that the present QFT (kinematic theory of fields) may serve merely as a limit of some \emph{dynamical theory of quantum fields}.
