Non-stationary states in quantum mechanics
In my quantum mechanics class (fall 2023), I did an in-class activity visualizing the motion of non-stationary states in simple 1d potentials. This was partially inspired by the impressive visualizations produced by my colleague, Michael Doering, and his students. I had each of the students provide a coefficient for one of the contributing energy levels. The result is a time-varying probability distribution that looks almost like a lava lamp. We did several rounds of this in class, just to see what kind of shapes we could create. Here are two example movies.
Infinite Square Well
Simple Harmonic Oscillator
Demonstration of the Photo-Electric Effect
Here’s a demonstration of the photoelectric effect built from materials scrounged at home. I built this demo while teaching Intermediate Laboratory (PHYS 2151) for physics majors remotely during the pandemic (spring 2021).
Workshop talk on “radiative corrections”
From my PhD days, QED radiative corrections have been one of my research “side hobbies.” Here’s a recording of a talk I gave at a workshop in the summer of 2022, investigating radiative effects in a type of experiment called a “Super-Rosenbluth.”
