| contents | Over the past several decades, dozens of tests have sought Lorentz violation in the nonrelativistic limit of the minimal matter sector of the Standard-Model Extension. Of the 132 Lorentz-violating degrees of freedom that are observable in this limit, 43 remain unconstrained. In this work, we demonstrate how existing experiments and data sets can be used to generate relevant sensitivities to all of these remaining degrees of freedom. We extract limits on all 43 of the previously unconstrained degrees of freedom and make additional improvements on 13 existing limits using published data. Our methods also offer the potential of improvements for 49 degrees of freedom in suitable future experiments. Further, the approach introduced here can be used to leverage data taken at different locations on Earth to achieve independent sensitivities to additional linear combinations of coefficients providing expanded discovery potential. |
