Hi I was wondering if someone could help me out. I have been studying TDPT and was wondering how it applies to atomic physics or if someone could give me a example that would be great.

The usual example given for TDPT is stimulated emission. You put a hydrogen atom which is in an excited state, and see that a time-varying electric-field perturbation will cause that hydrogen atom to spontaneously decay to a lower energy state, and therefore emit a photon.
