Question about light emission.

[cragar]

In the Aharonov–Bohm effect when charged particles are deflected do they emit light?

 

[mfb]

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.

The Aharonov-Bohm effect is a quantum phenomenon that describes the interference of charged particles in the presence of a magnetic field, even when the particles do not directly interact with the field. This effect has been extensively studied and has been observed in various experimental setups.

In regards to the question about light emission, it is important to note that the Aharonov-Bohm effect does not directly involve the emission of light. Instead, it is a result of the quantum mechanical nature of charged particles and their interaction with a magnetic field. Therefore, it is unlikely that light emission would occur as a direct result of the Aharonov-Bohm effect.

However, it is possible that in certain experimental setups, the deflection of charged particles could lead to secondary effects that could result in the emission of light. For example, if the charged particles are accelerated or collide with other particles due to the magnetic field, it is possible that this could result in the emission of light. However, this would not be a direct consequence of the Aharonov-Bohm effect itself.

In conclusion, while the Aharonov-Bohm effect does not directly involve the emission of light, it is possible that in certain experimental setups, secondary effects may result in light emission. Further research and experimentation would be needed to fully understand the relationship between the Aharonov-Bohm effect and light emission.
