PHYS 290: Quantum

Fall 2025

Instructor: Seth Major
Office Hours:

After each class, Thursdays 1:30 - 5 PM

Lectures:

MWF 10:00-10:50 AM Science Center G047

News:

  • Guide 6 is posted, now v1.7. Thanks to Yongfeng for pointing out the typos in the last problem!
  • if you wish you may submit a rewrite of the fourth problem of the midterm for additional points (up to 22 out of 25, whcih will be scaled). Submit these corections no later than November 21.
  • The Copenhagen event will also be an option. I'll post details in about a week.

Extras:

  • Want to play with the barrier/tunneling sim we saw in class? Here is the link to the PhET demo. It runs in Java so some installation may be necessary...
  • The 2025 Nobel Prize in physics was awarded for "for the discovery of macroscopic quantum mechanical tunneling and energy quantization in an electric circuit" and was discussed in an APS news story on the discoveries.
  • Extra practice questions for midterm.
  • The front cover.
  • Plot from the C60 interference experiment of Arndt et al, reference 35 in this paper: Am J Phys 71 (2003) 324.
  • Data from the He interference experiments: case 1 case 2 (pdf)
  • The PhET photoelectric effect webpage. (PhET's are nifty online physics simulations hosted by UC Boulder.)
  • On intsalling python (Thanks to Megan!)
  • Plots from the Aspect et al single photon interference experiment.
  • A webpage for python play.
  • Single and double slit intensity plots (pdf).
