25 Sept 2017: Lecture notes are posted.
For the last problem, there are several comments. 1. if you define the wave functions with the origin starting on one side of the box, you will have a constant term added to the dipole moment. This is an artifact of the choice of origin. Either you can define the origin to be in the middle of the box (giving sine and cosine functions), or you set the origin at one end and take only the time-dependent part. (I've worked it out both ways.) 2. you can assume the particle is an electron when you need a mass for calculating the energy. 3. Also, in the very last part, the numbers work out more realistically if you set the size of the box = 1nm instead of 0.1nm. This would be like a nanoparticle. Also note that the expression for the lifetime ( = 1/spontaneous emission rate) is in Svelto, and you use the time average of the dipole moment you calculate earlier in that problem.

Lecture Notes
While these notes are primarily to help me give my lectures, I'm posting them to help you fill in things you may have missed in class or to show the details of calculations we don't have time to work through. If you have any constructive input on how to make these more useful to read, let me know.
Note: if an instructor would like to make use of these slides, please acknowledge me. I would be happy to share the original .pptx files on request (email).
