Question about light emission.

Click For Summary
SUMMARY

The discussion centers on the Aharonov–Bohm effect and the conditions under which charged particles emit light. It is established that charged particles emit electromagnetic waves when deflected, but visible light emission requires high-energy particles and specific magnetic fields. Furthermore, light emission from charged particles necessitates acceleration, which can be achieved through electric or magnetic fields. Without acceleration, no light is emitted.

PREREQUISITES
  • Aharonov–Bohm effect
  • Electromagnetic wave theory

In the Aharonov–Bohm effect when charged particles are deflected do they emit light?
 
Science news on Phys.org
They don't have to be deflected - at least not for the interesting part of the effect.

If charged particles are deflected, they emit electromagnetic waves. To get visible light, you need very high-energetic particles and special magnetic fields.
 
so I can get an electron to emit light even if its not in a B or E field.

I don't believe so. I think MFB was referring to the fact that in the Aharonov-Bohm experiment the charged particles don't have to be deflected in order for the interference to be shifted. To get a charged particle to emit light you need to accelerate it somehow, such as with an electric or magnetic field. If there is no acceleration then there is no light emission.
