Time Dependent Perturbation Theory

We have used time independent perturbation theory to find the energy shifts of states and to find the change in energy eigenstates in the presence of a small perturbation. We will now consider the case of a perturbation that is time dependent. Such a perturbation can cause transitions between energy eigenstates. We will calculate the rate of those transitions.

This material is covered in **Gasiorowicz Chapter 21,**
in **Cohen-Tannoudji et al. Chapter XIII,**and briefly in Griffiths Chapter 9.
