# Charge acceleration without radiation

## TL;DR

This paper shows that electric charges can be accelerated without producing radiation, challenging a fundamental physics concept.

## Contribution

It proves that quantum mechanical charges can be accelerated without radiation via the Aharonov–Bohm effect.

## Key findings

- Quantum charges can be accelerated without emitting radiation.
- The Aharonov–Bohm effect enables acceleration without forces.
- This challenges the traditional understanding of radiation.

## Abstract

The existence of electromagnetic radiation—light, radio waves, microwaves, X-rays, and so on—is one of the most important physical phenomena. Their theoretical understanding is one of the greatest achievements of science, and our ability to manipulate them is one of the most significant technological achievements. Underlying this ability is our understanding of how radiation is produced: Whenever an electric charge, such as an electron, 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. This result gives a totally different perspective of how radiation occurs and opens the door to many possibilities.

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 the 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.
