Limit on Lorentz and CPT Violation of the Neutron Using a Two-Species Noble-Gas Maser
arXiv:physics/0007049 · doi:10.1103/PhysRevLett.85.5038
Abstract
A search for sidereal variations in the frequency difference between co-located 129-Xe and 3-He Zeeman masers sets the most stringent limit to date on leading-order Lorentz and CPT violation involving the neutron, consistent with no effect at the level of 10^{-31} GeV.
