Cory Rasor wins 2017 NSF Graduate Research Fellowship

Cory Rasor graduated from Colorado State University in 2015 with a Bachelor's of Science in both Physics and Mathematics. During his undergraduate career he worked with Professor Jacob Roberts developing a novel laser frequency stabilization technique as well as simulating electron trajectories for improved ultra-cold plasma trapping.

Following graduation, Cory was admitted to CSU's physics graduate program where he has been working with Professor Dylan Yost for the past two years. In this time, he has helped develop an ultraviolet laser system (121 nm) at CERN, in Switzerland, for laser cooling anti-hydrogen, the anti-matter equivalent of hydrogen. This project will probe what is currently thought to be a universal symmetry in physics and will ultimately be a stringent test of the Standard Model.

Cory has also helped develop a different, high power ultraviolet laser (243 nm) to be used for two-photon laser cooling atomic hydrogen, which will be useful for making high precision spectroscopic measurements. This work will help in understanding the so-called "Proton Radius Puzzle" and could help physicists resolve the discrepancies associated with it.

For his Ph.D. work, Cory is studying weak force interactions in atomic hydrogen and exploring how symmetry is broken by these forces. His proposed experiment has an opportunity to see effects of dark matter particles, and will also be a test of our current understanding of electroweak theory.
