Biography
Quentin G Bailey is generally interested in tests of our best current fundamental theory of gravity, the general theory of relativity, and tests of classical Maxwell electrodynamics. So far, I have been studying the theoretical and experimental aspects of testing Lorentz symmetry, the spacetime symmetry of Special Relativity. The motivation for this work is twofold. First, Lorentz symmetry is a cornerstone of modern physics. As such, it should be an experimental precedent to test this principle in as many ways as possible. Second, recent work on fundamental theories of physics, that attempt to unify the Standard Model of particle physics and General Relativity, has pointed to the possibility of deviations from perfect Lorentz symmetry. In the ongoing search for new physics, high-precision, typically low-energy tests of Lorentz symmetry offer a promising alternative to conventional high-energy accelerator experiments.
