Charge acceleration without radiation

TL;DR

This paper demonstrates that quantum particles can be accelerated without emitting radiation, challenging the classical understanding that acceleration always produces electromagnetic radiation, with implications across various types of radiation.

Contribution

It introduces a quantum mechanical effect where charges accelerate without radiating, based on the Aharonov-Bohm effect, prompting a re-evaluation of radiation principles.

Findings

Charges can be accelerated without radiation in quantum mechanics.

The effect relies on the Aharonov-Bohm phenomenon.

Implications extend beyond electromagnetism to other radiation types.

Abstract

The existence of electromagnetic radiation - radio-waves, microwaves, light, x-rays and so on - is one of the most important physical phenomena, and our ability to manipulate them is one of the most significant technological achievement of humankind. Underlying this ability is our understanding of how radiation is produced: whenever an electric charge is accelerated, it radiates. Or, at least, this is how it has been hitherto universally thought. Here we prove that quantum mechanically electric charges can be accelerated without radiating. The physical setup leading to this behavior is relatively simple (once one knows what to do) but its reasons are deep: it relies on the fact that quantum mechanically particles can be accelerated even when no forces act on them, via the Aharonov-Bohm effect. As we argue, the effect presented here is just them tip of an iceberg - it implies the need to reconsider the basic understanding of radiation. Finally, it seems clear that the effect goes far beyond electromagnetism and applies to any kind of radiation.
