A while back I saw a bunch of lovely visualisations of Lissajous curves that came out on the back of the Coding Train’s video on the topic. I very much recommend watching that video to learn how one might make something similar. Here I’m just going to present one attempt... [Read More]

Random motion with a saw-tooth potential

Recently I’ve been thinking about how an asymmetric periodic potential can result in net motion in one direction. In particular, I’ve been thinking about how muons hop around in crystalline materials such as Cr2O3. Possibly something like this: [Read More]
