Quantum Preferred Frame: Does It Really Exist?

TL;DR

This paper proposes an experimental test using EPR-type setups to investigate the possible existence of a preferred frame in quantum mechanics, challenging the relativistic invariance assumption.

Contribution

It introduces a specific experimental design to test for a quantum preferred frame, which has not been previously realized.

Findings

Proposes an EPR experiment with massive particles to detect preferred frames.

Suggests that such experiments can confirm or refute the existence of a quantum preferred frame.

Abstract

The idea of the preferred frame as a remedy for difficulties of the relativistic quantum mechanics in description of the non-local quantum phenomena was undertaken by such physicists as J. S. Bell and D. Bohm. The possibility of the existence of preferred frame was also seriously treated by P. A. M. Dirac. In this paper, we propose an Einstein-Podolsky-Rosen-type experiment for testing the possible existence of a quantum preferred frame. Our analysis suggests that to verify whether a preferred frame of reference in the quantum world exists it is enough to perform an EPR type experiment with pair of observers staying in the same inertial frame and with use of the massive EPR pair of spin one-half or spin one particles.
