Okey, so I´m taking a course in QM and I feel that I got a grip of most of it.(adsbygoogle = window.adsbygoogle || []).push({});

But then we arrive at this formulea [tex]

i\hbar\frac{\partial}{\partial t} c_n(t) = \sum_m \hat{V}_{nm} e^{i\omega_{nm} t}c_m(t),

[/tex] where [tex]

\omega_{nm} \equiv \frac{(E_n - E_m)}{\hbar}.

[/tex]

In other words time dependent pertubation theory. And I just feel confused. I dont know how to start tackle it with my intuition.

What are, in your opinion, the first intuitional things I should remark when it comes to this equation? What does it tell about my physics without having to do some big derivations?

Thanks!
