This summer my friend Lisa Larrimore and I are working with Dr. Amy Bug in the Swarthmore College physics department. Our research invloves developing computational models of positronium, using path integral monte carlo techniques. We are programing in Fortran 90, and processing our data using Kaleidagraph ^tm and IDL^tm.

Until I put more content up, you can get an idea about our work by looking at Amy Bug's homepage.

Lisa and I prepared a powerpoint presentation on our summer research to present to other researching faculty and students. Lisa has modified the presentation into a web slide show which you can see on her research page.

I have spent over half the summer working on simulating the behavior of positronium in an electric field. See the five graphs that are the fruit of six weeks' labour. :-)

This data came from a single-particle simulation of a positron in a harmonic potential.

This is from a benchmark run to test our positronium simulation. Instead of the normal Coulombic (or Yukawa) interaction between the electron and positron, we used a simple harmonic oscillator.

Lately I have been trying to compile a single program that is flexible enough to carry out all of the tasks we need. This graph is the result of a test of this new code against previously tested code.
