AN ODD (PARITY) TEST OF LORENTZ SYMMETRY WITH ATOMIC DYSPROSIUM

We propose using a Stark interference technique to measure directly the odd-parity c_0j components of the electron sector c_μν tensor of the Standard-Model Extension. This technique has been shown to be a sensitive probe of parity violation in atomic dysprosium in a low-energy, tabletop experiment, and may also be straightforwardly applied to test Lorentz invariance. We estimate that such an experiment may be sensitive to c_0j coefficients as small as 10^−18;.
