Phys. Rev. Lett. 102, 010402 (2009) [4 pages]Prospects for Large Relativity Violations in Matter-Gravity CouplingsReceived 8 October 2008; published 5 January 2009 Deviations from relativity are tightly constrained by numerous experiments. A class of unmeasured and potentially large violations is presented that can be tested in the laboratory only via weak-gravity couplings. Specialized highly sensitive experiments could achieve measurements of the corresponding effects. A single constraint of 1×10-11 GeV is extracted on one combination of the 12 possible effects in ordinary matter. Estimates are provided for attainable sensitivities in existing and future experiments. © 2009 The American Physical Society URL:
