C. J. Auton conducts experimental nuclear physics research using beams of neutrons to probe fundamental symmetries of nature. A central focus is searching for violations of time-reversal and parity symmetry (deviations from how physics behaves under mirror-reflection and reversal of time) by measuring how polarized (spin-aligned) neutrons pass through and react with atomic nuclei such as lanthanum-139. The work also involves developing detection instruments and neutron interferometry techniques at large facilities.
