This week, as a natural progression in this class, we are going to transition from studying spatial wave-functions to studying spin. This is part of a transition to more formal aspects of this class in which we use operator formalism. Will we use operators, e.g., raising and lowering operators, in both our study of spin and in our reexamination of the harmonic oscillator using operator formalism.
This survey asks how abrupt you would like that transition to be? Are you tired of spatial states and would you like to transition to spin states ASAP? Or we you prefer a bit of review of 1, 2 and 3D QM before we transition to studying spin?

Midterm 2 solutions
Here are solutions to midterm 2. I see that I did not write it in the solutions, but it is helpful for sp2 type integrals to recall that \(\...

I am thinking that the HW this week is not so excessively long as last week's assignment. This week's HW has a problem involving a t...

For tomorrow's class we will start a new topic, which is free particle propagation and scattering. This involves non-local states.

Solutions below. Homework 8 includes spin problems and problems using spin matrices. Basically, what are called two level systems.
