Tuesday-Thursday. QM in 2 dimensions. Includes wave-functions and notes.


On Tuesday we will start a new topic: quantum mechanics in two-dimensions. Things change as we go from 1D to 2 or 3 dimensions. Degeneracy is a big part of that. There is degeneracy in the 2D harmonic oscillator and in the hydrogen atom. Energy eigenstate degeneracy is critical to the phenomenology of our world, including semiconductors, biology, chemistry etc.

On Tuesday will will talk about the 2D harmonic oscillator. Much of what we will learn will help pave the way for understanding the hydrogen atom a bit later this quarter.
Added: also E2=2ℏω,  E3=3ℏω ... (see list in picture below)

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 \(\...

  • Square Well boundary conditions.
    This video shows how to use boundary conditions along with the time-independent Schrodinger equation
  • HW 7 with solutions.
    Please turn in HW 7 to Michael Saccone's mailbox in the physics department mailroom by 6 PM on Monday,  May 20
  • Discussion of problems 5 & 6, HW4.
    April 24: Thanks to some awesome work by students in this class, I have some information on wave-functions and their parameters for the 2-s...
