AMP research on atomic clocks and quantum optics includes precise tests of fundamental symmetries of physics (Lorentz invariance) linked to questions about the origin and fate of the universe. In particular, these measurements can be used to test the standard models of physics, with profound implications for cosmology. This research also enables Very Long Baseline Interferometry (VLBI) astronomy and precise navigation of spacecraft. Measurements on low temperature collisions between hydrogen atoms contribute to the understanding of basic atomic processes.
