Toward Nonlocal Electrodynamics of Accelerated Systems

TL;DR

This paper explores nonlocal electrodynamics in accelerated systems, proposing an extended theory with quadratic terms in the acceleration tensor to preserve parity, and discusses its physical implications.

Contribution

It introduces an extended nonlocal electrodynamics framework including quadratic acceleration terms to maintain parity conservation.

Findings

Quadratic terms in the acceleration tensor can preserve parity in nonlocal electrodynamics.

The extended kernel depends on the acceleration tensor and vanishes without acceleration.

Physical implications of the quadratic kernel are briefly discussed.

Abstract

We revisit acceleration-induced nonlocal electrodynamics and the phenomenon of photon spin-rotation coupling. The kernel of the theory for the electromagnetic field tensor involves parity violation under the assumption of linearity of the field kernel in the acceleration tensor. However, we show that parity conservation can be maintained by extending the field kernel to include quadratic terms in the acceleration tensor. The field kernel must vanish in the absence of acceleration; otherwise, a general dependence of the kernel on the acceleration tensor cannot be theoretically excluded. The physical implications of the quadratic kernel are briefly discussed.
