Let's say that you've got a time-dependent perturbation to your potential (say, the particle-in-a-box to make things simple). Say you start in energy eigenstate #3. What's the probability that the particle will stay in eigenstate 3 after time T?(adsbygoogle = window.adsbygoogle || []).push({});

This is not a homework problem. I'm not understanding the equation for the probability which seems to give a number larger than 1.
