I would like to perturb the wave-function of a localized charged particle with a potential that is close to a delta function in space and time. Do Maxwell's equations prevent such a potential in theory if not in practice?(adsbygoogle = window.adsbygoogle || []).push({});

If so can I in a very loose sense think of the potential as giving the wave-function a localized sharp "kick"?

Thanks for any help!
